I inherited this 50 cal flintlock from my wife's uncle when he died well over 30 years ago. There is no brand name on the barrel, only a big capital I inside a box, black powder only and made in Italy below that and a serial number and proof marks. I have killed deer with it, it is a nice gun with pretty wood and furniture. These pictures are not good due to reflection from the barrel but maybe someone has an idea who made it.
