When I met the gentleman to trade for this rifle he told me that his grandfather was in WWII and picked this and another item up and got them back home. There is no import marks on the rifle at all. The other item was Nazi dress sword just like this one:
He showed me a portion of the sword that his grandfather showed him that had some discoloration (turned green). His grandfather told him that was corrosion from the blood that was on the sword. Judging from the patterns of the corrosion it was pretty easy to see how this could have been laying in blood before being picked up. If the rifle was alone then I might've had some doubts as to its authenticity but the two paired together suggested that his story was true.
it's true there are no Nazi markings on the rifle like there are on my Walther P38 and K98 and I inquired other places as to why this is. I was told by others who know much more about this than I do that these types of rifles were for training Hitler Youth and rarely had Nazi symbols struck into them. Unfortunately there's very little information out there regarding this rifle but I'm still looking.
