Very nice unit and in excellent condition as many of the Turkishguns were just beat to snot.
I cannot see if you have the AA leg, as the drum chest is in the way.
The traverse stops will be hard to find.
I have only seen a couple of sets of traverse stops on the loose and one is shown so you can ID it if one shows up. I believe the late Rick Cartlege did an article on the Turkish tripod in Small Arms Review some time ago.
I assume you have the 08/15 drum bracket: picture attached, as it is not shown but it would be on the other side of the gun as shown.
I've also attached a picture of the traverse stop both on and off the gun and the Turkish drum bracket, which I assume you have, as I see a nice 08/15 drum sitting in an original chest.
