A welcome to ya Big Buck, and I pray you get many more.
To answer, a good place to start is right here. Thars' a bunch a folks that study them ole guns that hang-out here from tyme ta tyme,and many will be willing to share what they know. It's the "net" so info is free. Maybe we can answer basic questions and offer guidence so when you do speak with a"pro" you'll know what he's talking about.
It's the holiday season and many are busy, so replies may be a bit slow,,but I recomend giving what ever info you have about a firearm in question a throw right here. Do'm one at a time,,photo's will sure help,but, stuff like barrel stamps,words,,dates, length,bore size,brass, flint or cap,,,
example; I have an 1836 prussan flint that is an 1839 cap conversion; three band .72 cal muscket, the infrantry number on the Butt is stamped 732, can anyone help with shipping dates?
or; I have an olde gun that say's Thompsomthing? on part of the barrel and the only numbers I can read look like 6764?? It's got a brass trigger guard, and a hole on the side of the back part of the gun, looks like somthing used to fit in there. I think it was made to shoot round ball.
See? welcome to ya BB
This is a good place,,(please don't take my post wrong,,I'm just meeting you and mean no offence,,after all it is the net) luck to ya,
