I found this in a local shop. I usually don't buy toys but this was neat. It is a bit more than a toy but not a real gun. It is made to shoot percussion caps and has a steel sleeve around the barrel that appears to be the diameter to hold a M1816/1822 US spike bayonet. The trapdoor bayonet and M1858 Springfield are too small. I don't have an 1816 bayonet and had to borrow a musket to compare. It has casting numbers on the lock and hammer but I do not see any other marks.
Has anyone seen one?
