Touching off a few 36 cal muzzleloader rounds with a beautifully crafted 300? year old flint lock/primer cap converted. The trigger was great, the wood & metal work amazing. No real way to date it. It did have a rifled bore. When younger I got to shoot Singer 1911, snuck back from WWll? & didn't realize what I had. The Germans made some way cool military rifles/pistols/sub machine guns/ tanks.... V2. I like the US stuff too.
