I have this Old Steyr Mannlicher and I cant find anything like it. My Greath Grandfather Says he bought it in Germany.. See the pics I attached anyone direct me where I can find info.
SteyrMannlicher in Austria should be able to provide you with any information you desire. The stamp in the wood indicates that it was at one time sold by W. Triebel in Spandau, Germany (near Berlin). Trieble was or is a master gunsmith specialized in shotguns.
