Woody's FAIRBANKS AND
COLE Friction Tuning Peg Page
I am looking for a source for actual-era
replacement pegs for
my grandfather's 1885 Fairbanks and Cole five-string banjo
If you know of a source or someone that could make
them,
please CLICK HERE to
email me (Woody).
I am not 100% sure but I believe these to be made
from prehistoric ivory
although there is a chance they could have been made of bone.

Approximately 70 percent of bone and ivory is made up
of an inorganic lattice composed of calcium phosphate and various carbonates and
fluorides.
The organic tissue of both bone and ivory is ossein and it constitutes at least
30 percent of the total weight of the material.
It is often difficult to distinguish between bone and ivory unless the material
is examined microscopically.
Bone is coarse grained with characteristic lacunae or voids; ivory is a hard,
dense tissue with lenticular areas.
Both bone and ivory are easily warped by heat and moisture and are decomposed by
prolonged exposure to water.
In archaeological sites, ossein is
decomposed by hydrolysis, and the inorganic framework is disintegrated by
acids.
In waterlogged sites, bone and ivory can be reduced to a sponge-like material;
in arid sites, they become dry, brittle, and fragmented.
In some circumstances, bone and ivory can become fossilized as the ossein is
replaced by silica and mineral salts.
Archaeological bone and ivory can only be cleaned, strengthened, and stabilized;
satisfactory restoration is often impossible.
