This pistol likely is one of the better tourist items from the pre-1960 era. Built with a newer stock, but using an original lock, barrel, and ball trigger. They were built this way for the tourists while there were still a supply of original locks and barrels available locally. The brass axe head, and likely the brass trigger guard were likely added by some hobbyist later in the 20th/21st century. The hobbyist not knowing that ball triggers were rarely used in conjunction with trigger guards. The lock on the pistol is a very common Balkan miquelet from the period. And the barrel looks the same. Definitely not a $900.00 gun. Maybe $3-400.00 for the lock, barrel, and trigger. JMO I have a similar pistol less the axe and guard.
