The C. F. Martin Orchestra Model
Guitar

The 1930 Martin 000-28 O.M.
Orchestra Model and OM-45 DeLuxe
Until 1929, all six string Martin guitars had necks with 12
frets clear of the body. As the tremendous popularity of
the four string tenor banjo waned, banjo players started to seek
out guitars with access to more frets, emulating the longer
necked banjo.
Martin's first attempt to build a guitar with 14 frets clear of
the body, to provide greater access to the upper frets, was
achieved by simply attaching a longer neck to the four string
Martin tenor guitar at the 14th fret, and moving the bridge
upwards to compensate. This bridge placement, however,
produced a tone that was less than ideal.
By late 1929, Al Esposito of the Carl Fischer stores suggested
an alternative, ordering a tenor guitar, which became known as
the Carl Fischer Model, which added access to two extra frets by
shortening the guitar's upper bout.
Soon after, Perry Bechtel of the Cable Piano Company, visiting
the Martin factory to meet Mr. Martin for a fishing trip and
seeing the Carl Fischer Model, requested a fourteen fret clear
six string version of the Martin 000-28 guitar, and the
Orchestra Model was born.
For many years, Bechtel was credited with conceiving of the 14
fret neck Martin guitar, while it was actually Mr. Esposito who
sketched his concept of the new model, complete with shortened
upper bout, and Mr. Bechtel's contribution was dependent on the
grace of a fishing trip!
Note that the early Carl Fischer model has a tiny upper bout and
no pickguard. Soon after, the upper bout was widened and a
pickguard added, and the resulting tenor guitar was eventually
cataloged as the standard 0-18T still produced today. The
original OM prototype ordered by Perry Bechtel has remained
unseen in modern times. The guitar was paid for and was
the property of the Cable
Piano Store, and was most likely destroyed in a massive
fire which gutted the building. We may never know if it
also may have had the smaller upper bout. Several of the
early OM-28 were also ordered with no pickguard.

1930 OM-45 DeLuxe, 1930 000-28 O.M. Orchestra Model, 1930 OM-18,
1930 OM-18P, and 1929 0-18T (Carl Fischer Model - Gear Pegs)
The OM-28 was soon followed by the OM-18, and the OM-18P
Plectrum Guitar appeared in 1930. The long necked plectrum
seemed a natural, since the OM was specifically made to suit
banjo players who were used to a long neck, and who were moving
to the guitar to match changing tastes. In 1931, Martin
added a handful of plectrum guitars in the C-1 and C-2 round
hole archtop styles. By the end of 1931, Martin had built
it's last Plectrum Guitar.
By 1930, the Carl Fischer Model had become the standard
0-18T. Many of the Carl Fischer mode instruments were in
fact sold to other stores. By 1934, what was formerly
known as the OM-18 and OM-28 had become the standard Martin
000-18 and 000-28.

The 12 Fret 1929 000-28 and early 1930 OM-28
This 12 fret 000-28 was stamped on the first of May in 1929,
just days after Martin had stamped the first 14 fret neck clear
Carl Fischer tenor on April 20.
The first guitar built for Perry Bechtel:

The following photograph illustrates the evolving body shape of
the early 14 fret tenor guitars. Note the smaller and
rounder upper bout of the Carl Fischer Model.

A 1928 Martin 2-18TL, Martin's first attempt at a 14 fret tenor
guitar, a 1930 Martin Carl Fischer Model with OM style
pickguard, and a 1930 Martin 0-18T with wider upper bout.
This OM-28 shows transitional features that are seen on the
earliest OM's: banjo style tuners, a pyramid style bridge, a
small teardrop shaped pickguard, and a rare 1 13/16" wide neck
that was requested by Perry Bechtel for his personal guitar, and
has been seen on only a couple of others.
While not as pronounced as the Carl Fischer, the early OM from
1929 and 1930 presents a slightly rounder upper bout than later
OM and 000 Martins which intersect with the neck at a
perpendicular with a nearly 90 degree angle.

000-28 Orchestra Model
Beautiful original condition early OM from the second batch of
five - the first stamped in January of 1930.
One of the handful of original OMs built with a pyramid bridge,
teardrop pickguard, and banjo style tuners.
While the 000-28 12 fret had a 1 7/8" wide neck, the new OM
model had a 1 3/4" neck. The original example built for
Perry Bechtel, and possibly one or two of the others of the
roughly dozen or so built in 1929, had a 1 13/16" wide
neck.
This is the only 1930 example I know of to have the 1
13/16" wide neck.
An historically important transitional guitar combining old
world craftsmanship with the sound and playability of a modern
14 fret long scale guitar. Recently brought to
absolute optimum playing condition by OM specialist T.J.
Thompson. TJ installed new reproduction tuners, for which
he aged the buttons, to save old tuners. The vintage
tuners in fine shape are preserved in the case. TJ
proclaimed this to be about the nicest OM of the many
he's seen.
Serial number 40932
Stamped January 11, 1930

This guitar, built in January, 1930, was listed as a 000-28/OM
Orchestra Model
This case is somewhat of a mystery. I originally thought
it might have been ordered for a long and narrow necked plectrum
guitar, but the neck on this case is a good 4" too long for even
a plectrum OM. It was most likely the result of a
miscommunication or miscalculation in ordering a case for a
strange and newfangled guitar before ordering for a 14 fret
clear body had become routine
The Evolution of the Name
Here you can see the evolution of the name of the Martin
O.M. The first couple of individual examples in 1929 were
listed in the Shop Orders as
000-28 Perry Bechtel
followed by a small batch listed as
000-28S Perry Bechtel Model
(The "S", was used to indicate "Special", as in "Special
Order". It was later used to indicate a "Standard" 12 fret
vs. a 14 fret.)
We then see a Shop Order for five listed as
000-28P Perry Bechtel
(the first 14 fret Plectrum)
and then
000-28 O.M. Perry Bechtel Model
This is the first listing to include the designation "O.M."
Then we see the Shop Order for five including mine, the first of
1930, listed as
000-28 O.M. Orchestra Model
This is the first instance where the name Perry Bechtel is
replaced with the term "Orchestra Model".
And then we see the first six string 14 fret 18's, logged
as 000-18 O.M.
and 000-28 O.M. O Model
and finally quite a few batches listed alternately as 000-28 O.M. or 000-18 O.M. or O Model 000-28 or O Model 000-18
It wasn't until March, when the first two OM-45 were built that
Martin dropped the "000" from the name and called them OM/45 and then OM/28.
But even after this, Martin made a batch of Plectrum Guitars, 000-18 O.M.
Plectrum

The left handed Plectrum guitar in Shop Order #558 is included
to show that this is not necessarily an Orchestra Model, as
proposed elsewhere. It seems to be a Standard
guitar. All of the other Orchestra Models were labeled as
"Perry Bechtel" at the time, while the Standard 000 were not.
Shop Orders #557 and #634 are the first orders listed as
Plectrum Style Orchestra Model Guitars, built with 15 frets
clear in rosewood and mahogany respectively. These proved
to be popular with the former banjo players in jazz bands, and
plectrums account for a good number of the OM Guitars.
As you can see, the name was a moving target, evolving with
every batch. We used to think there was something special about
the 1929 "Prototypes", but the OM was constantly evolving
through it's first year or so, and there is really nothing more
distinctive about the 1929 examples than early 1930 ones.
These were a 000 size guitar, and "Orchestra Model" was the
designation for the new 14 fret body shape. In fact, the first
D-28's with 14 fret necks were listed in the catalog as "D-28
Orchestra Models". So they were recognized as being different
from the beginning, the only significant change being a
shortening of the name from "000-28 Perry Bechtel" to "000-28
O.M." to "OM-28".
Only the earliest OM-28 have pyramid bridges. For many
years the common wisdom said that only the few OM-28 from 1929
had pyramid bridges. In truth, Martin switched to
the belly bridge in March of 1930. M
any of the earlier OM-28 remained in the factory unsold due to
slow sales of this new model during the Depression, and were
also given belly bridges before they left the factory.





OM-18

In January of 1930,
shortly after introducing the rosewood Orchestra Model
version of the 000-18, Martin built the first two single
examples of the OM-18, an Orchestra Model version of the
000-18 with mahogany back and sides.
The following orders were for OM-18 Plectrum guitars, so
they seem to have been focused on the Style 18 Orchestra
Model as their Plectrum guitar.
After a Shop Order in March for five Plectrums, we only see
an order for three regular OM-18 in April, and then Martin
didn't produce another order for six string OM-18 until an
order for three guitars in April and then no more orders for
OM-18 until a single guitar in August. A month later,
we finally see the first real batch of 10 ten guitars in
mid-September.
As you can see, the first OM-18 were very slow in
coming!

Karl Farr, who played
guitar with Roy Rogers in
the "Sons of the Pioneers"
played what had to have
been one of the original
two OM-18. It has a
small rectangular bridge,
while all of the later six
string OM-18 were built
after the switch to the
belly bridge.
While everyone is
convinced that these two
guitars must have had a
pyramid bridge, Martin
discontinued
the pyramid
bridge on a
Style 18 in
1926, and
replaced it
with a plain,
straight
rectangular
bridge.
The two OM-18
built in early
1930 would
have the
plainer style
bridge.
Photos of
Farr's guitar
show what may
look to be a
pyramid
bridge, but
more careful
inspection
will show that
it is in fact
a replacement
bridge
with
plain wings.

O.M. SCALE
The OM-18, like
all "Orchestra Model" Martins, were built with a 14 fret
neck with the longer 25.4 inch scale which was borrowed
from the 12 fret 000, and which was later adopted by the
Dreadnaught.
Most folks
believe the
narrative that the
OM was a long 25.4"
scale
guitar, which was
discontinued and
replaced by the
short 24.9" scale
000-18. While
the long scale was
referred to as the
"O.M. Scale", the 12
fret 000 was and
continued to be a
long scale
guitar. In
January, 1934,
Martin simply
reclaimed the OM as
the "Orchestra Model
000", as it was
overtaking the
traditional
"Standard" 000 in
sales, but it
remained a long
scale guitar.
It was Martin's
custom at the time
to produce it's
largest size guitar
with a long
scale. Before
the 000, the 00 had
a long scale.
On September 12,
1934, Martin moved
the 000 to the 24.9"
"O Scale", as the
new and larger
Dreadnaught replaced
the 000 as their
long scale guitar.

As you can see, the 000 was moving from long to standard "0
scale" just as Martin was ramping up production of the
Dreadnaughts, which was replacing the 000 as their long scale
guitar in their product line, moving from batches of three, to
six, to 12 guitars per shop order.
1930 Martin OM-18
Serial number 43985
Stamped September 13, 1930
This original condition early OM-18 is from the first batch of
ten - made in September of 1930, following the first two
examples built in January, and three built in April and
followed by a number of batches of 25.
One of the early original OMs with a teardrop pickguard and
Grover banjo style tuners:



3lb. 1.2 oz.
The earliest OM-18 guitars are extremely light weight, with thin
backs and sides, which makes it rare to find an example without
multiple cracks in the mahogany.
Martin appears to have been mindful of matching the pickguard to
the guitar, as the early mahogany OM sports a rather solid dark
blood red pickguard, while the contemporaneous rosewood OM-28
sports a brownish pickguard with large swirls.




While some collectors have
been on a quest to find one of the early OM-18 with a
pyramid bridge, Martin discontinued the pyramid bridge
on a Style 18 in 1926, and replaced it with a plain,
straight rectangular bridge, so I believe the two
OM-18 built in early 1930 would have the plainer style
bridge.
1933 Martin 0M-18
Serial number 54864
Stamped December 4, 1930
3lb. 4.2 oz.
This later example, from the final batch of OM-18's, stamped in
December of 1933, has a full size pickguard and regular
clipped-end Grover tuners, the first design to follow the banjo
style tuners.





The later OM-18 is one of the first Martins to have the gold
Martin logo on the front of the headstock. These early
logos are gold leaf and without the black border found on the
later gold decals.

These transitional guitars have both the gold logo on the front
of the headstock as well as retaining the stamped Martin logo on
the rear.

1930 Martin OM-18P
Serial # 44556
Stamped October 24, 1930


1930 Martin OM-45 DeLuxe
Serial # 44070
Stamped September 25, 1930

Priced at $225 at it's introduction in 1930, the OM-45 DeLuxe
was Martin's most expensive production guitar, a step above
the Style 45, with inlaid pickguard and bridge, and engraved
gold tuners with pearl buttons. Martin carefully selected
finer woods and other materials for their highest quality
guitars. The quality of materials, with perfectly
consistent matching pieces of pearl throughout, is higher on
this guitar than on any other Style 42 or 45 I have seen, from
the 19th or 20th Century.
The first example, purchased used by Roy Rogers for $30 during
the Depression, had a somewhat different design on the
pickguard.
The DeLuxe was discontinued within a year, after a handful of
individual examples and three batches of three, due to Martin's
inability to source the distinctive DeLuxe parts.
This example is one of five known to exist today.



The OM-45, with it's solid headstock, initiated a slightly
simpler torch design than was seen on previous Style 45 Martin
headstocks.



Eleven OM-45 DeLuxe were built.
The first OM-45 DeLuxe was one of two built as standard OM-45
stamped on April 9, 1930 to which the inlaid fingerboard and
bridge and gold plated tuners with pearl buttons were
added. Unlike the first D-45 which cowboy star Gene Autry
ordered from Martin, this first OM-45 was said to have been
bought by Leonard Slye before took the name of his cowboy star
persona Roy Rogers.

The first actual shop order for a DeLuxe was for a guitar set up
for Hawaiian playing, Stamped on July 26, 1930.

A few days later a batch of three was stamped. Notice,
however that four serial numbers were accidentally listed: 461,
462, 463, and 464.
#73461 was accidentally duplicated from shop order 744.
This caused Mike Longworth to count one extra OM-45 DeLuxe.

The first batch of three was stamped on September 23, 1930

The final batch of three was stamped on November 28, 1930.

Mike Longworth made one more mistake, accidentally listing this
shop order twice, once as 44999-001, and once as 44499-44501.
We have long accepted Longworth's faulty number of 14 OM-45
DeLuxe.
Beside counting three twice, and counting one extra, he also
overlooked the original OM-45 DeLuxe since the shop order listed
a regular OM-45!
