Appears to me that where the frizzen is broken off it looks like pot metal. The frizzen spring also looks like it is molded to the lock plate. Looks like a wall hanger toy to me. Seems to me anyone holding it could tell if it’s a real firearm or a pot metal gift shop decorator. Lord have mercy
Was advertised as antique black powder pistol at an online auction. I found that (exact, I think) non-firing replica in the link above for $59. Auction ended at $152 plus tax and shipping.
