Your statement is interesting. Was Schmeisser captured by the Russkies at the end of the war and brought back to Mother Russia?
Yes, he was.
While there, I'm quite sure Schmeisser was most eager to please and more than willing to let anyone else take credit for any and all of his work on what eventually became the AK-47.
How much impact he actually had on the design, we will never know for sure but it is doubtful the Russians of 1947 would be too eager to give credit for their primary assault weapon to an ex Nazi, regardless of his talent.
Yes.
He was on “Kalashnikov’s design team”.
