Martin continued to use the "bell end" Waverly WG-31 tuners into
the 1960's on their 12 fret "New York" guitars. These can
be distinguished from the earlier WG-31 tuners commonly used in
the 1920's by a larger end piece holding the end of the tuner
button shaft that broadens at the base.

IDENTIFYING
TUNING MACHINES FROM PHOTOS
In
my pursuit of the ridiculous, and my never ending quest
to discover distractions to keep me from doing the
important things I need to do, I’ve discovered some
obscure clues to help identify Martin guitars,
especially the earlier ones which are frustratingly
similar from decade to decade, and did not have serial
numbers.
The
original tuners can sometimes help us identify the age of
an early Martin when the guitar is not in hand and we have
limited information.
Martin used Jerome tuners on all of their pre-1867 guitars
with machines and slotted heads, and Seidel tuners on all
of their post-1867 19th Century guitars with machines.
Ivory pegs on solid heads were a no-cost option.
Unfortunately,
most people photograph the top and back of the headstock,
but don't photograph the side of the headstock to give a
clearer view of the tuners. Fortunately, with a sharp eye,
we can also identify the tuners by the size and shape of
the end piece that the tuner shaft is peened into, as well
as the relative size of the peen.
Until about 1902, all Jerome, Seidel, and the earliest
Waverly tuning machines also had a peen attaching the
tuner button to the shaft, which we don’t find on these
later, more modern tuners.
On
Jerome tuners, the end piece has a round top, with the
peen covering most of the area.

The similar "Bell-end"
Waverly tuners from the 1960’s can be distinguished by the end
piece which has a large round top and widens near the
base. The peen is small.
