I got this piece from a gent who's great grandfather was issued this as a sidearm when he graduated West Point. Over the years it has seen it's share of abuse. The loading gate is missing, the hand is missing and the hammer was partially wrecked, the bbl lock was stuck in the closed position + a bunch of other minor stuff too. The 1st step was getting it apart (stripped and bent screws) and the next is/was the hammer repair. I made the replacement piece out of the end of a hoof rasp, I soldered it with hard silver solder. Pic's below a before and after on the hammer.
