Hi Rick!
Very nice pistol .I believe that is an authentic one, possibly made in balkan area for the ottoman market.
The lock doesn't have the quality of European locks, it reminds work made in Balkans.
The barrel it looks European to me but I can't see the marks very well.
The only thing that looks new to me is the mother of pearl that has on the back side.
Can you please share the dimensions of it? Those pistols usually are 36cm to 40cm.
After all you have an excelent pistol.Well done!!
Aristeidis.
