Nuts on C. F. Martin Guitars
Ebony Nuts
While the nuts on most Martin guitars were made of ivory, many were
made of ebony, especially on Style 15 and 17 guitars, but also on many
Style 18 guitars including the OM-18.
It is less known that the many of the earliest and finest guitars made by
C.F. Martin himself were made with ebony nuts.

1840's Spanish Style Martin guitars.

Many Martin and Martin & Coupa guitars from the 1840's had
nickel silver nuts, which I've noticed came in three different
thicknesses, measured from the end of the fretboard to the headstock:

Pearl Rosette zig zag border size 1
11/64" metal nut

Ivory Nuts
All standard rosewood Martin models have ivory nuts.
Many of the ivory nuts on 19th century Martins were quite thin.

Martin 1870's 1-28
1874 Martin 1-28

The shapes of nuts varied quite a bit over the years, but tended to become
more rounded and angled.
Martin 1897 1-21
Martin 1907 1-28
1913 Martin Foden Special Style E
1917 Martin 0-30
By the late teens, Martin nuts were thicker, finding the form they would
continue with through later years.
