Not gonna lie,that's the most unique (i believe that's the right word.) black powder rifle i have saw so far.One gripe from me is why is a 1776 model rifle a percussion cap model?Didn't the cap come along in the 1830's and before that it was a Flintlock?
cap came along in the 1820`s , and as far as I know there`s no such thing as a flint lock mowrey ! interesting considering all the box lock flint pistols that were made! [hmm]
I was close lol i think the Mowrey would look better with a flint (doesn't every gun?).
