I am new to this forum and think I now know what a DSM34, a Sportsmodel and what KKW's are. I learned to shoot with a KKW Gustloff my dad found in Paderborn Germany during WW2. I just purchased a Walther, Sportsmodel (stocked like a DSM34) with a scope and KKW type sling. The serial number of the rifle is 41xxx w, with the spread eagle over n proof. The block style scope mounts to the receivers grooves, is a see thru mount with a slight offset and the mount is tightened to it using a squared key I have. The scope is marked ZIELMI, over Nr4289, over a CARL ZEISS / JENA. My question - Is this a pre KKW German snipers training model or ??? Do I understand correctly that all of these pre KKW training models were military trainers and the differances are distinguished from what clubs used them? Thanks for all of your time. .... I also have a DSM34 with a very small propeller stamped on the barrel. Is this a club stamp?
