Here's one more pic. Better pics and more detalis will come when i have the gun in the hands, these are pics the seller made.
As fare as i know Fritz Wendel gone after the war from Suhl to Ulm, he learned to be an gunsmith in Suhl.
I have two Büchsenmacher/gunsmiths named Wendel in Suhl before 1945, Robert and Ferdinand, in the moment i dont know if they are familar related to Fritz Wendel.
Fritz Wendel had an company named " Fritz Wendel KG, Jagd- und Sportwaffen, Ulm Söflingen",documented in 1954.
I found two of this guns located in the USA, both bought by US Army members around the 1950s in the shop in Ulm and later exported to the USA. These two are only shotguns.
