Hi Two Flints,
I noticed you have access to lookup serial #'s. If it's not to much imposition I have a few I'd like to know more about.
1865 Spencer
Gwen & Campbell ( Union Rifle) carbine
Starr carbine 9284
Burnside carbine 5th model
Smith Carbine
I currently shoot the Burnside and Smith and am having bullet moulds made for the Starr and Gwen&Campbell so will be shooting them in the near future.
