Basic Banjo Anatomy "How to find your way around the round
thing" Let's look at some basics about banjo anatomy, and then
how to find the serial number. The two main parts of the banjo
are the Neck and the Pot. The Neck has the frets and a headstock
with tuners. The Pot is the round part and everything connected
to it. The resonator is the "Back" of the banjo, normally held
on with either 3 or 4 Thumbscrews. The Thumbscrews are visible
from the top, and very easy to remove, which allows the
resonator to come off: Once you get the resonator off, you can
look for a decal and/or serial number inside the rim: This is a
Mastertone decal, used from the mid 1920's to through the 1930's
A typical serial number (Factory Order Number) stamp from the
