Stamp on a Turkish muzzle loader

[archer]

Rand, this doesn't hold a candle to your museum piece, obliviously made for royalty.
This lock is typical of the era, it shows abuse and an excellent sear repair. unlike most most exposed metalwork of the era the thimble and trigger guard are not embellished the screws are all cut square opposed to V cuts of English guns.

I've included a shot of a German jaeger comparison. This gun is stout and shoulders very steady, it's almost as though the inlays covering up it's origin.
Oh, other than seeking out a turkish speaking person who reads arabic, how can I solve the mystery as your trying to do?
