Yeah, I remember those non-shooting "decorator" replica flintlock pistols and rifles that came from somewhere in the Moslem/Arabic/North African/Middle Easteern part of the world back in that time period. They were pretty light-weight and non-functional, and with many of them you could tell they weren't real just by looking at them...they were just kind of off and "wrong" looking. Sort of like the real cheaply made fake swords from this area, Asia, and even Mexico you used to see that were basically made out of old thin scrap sheet metal.
Does the lock and trigger function on this pistol, and is the barrel drilled all the way down with a flash hole drilled through from the pan?
Besides the decorator replicas, in many places traditional, antique and antique style firearms like this were still being used and made up until fairly recently.
