Correct John, I've been on the look for a Spuhr or Werle for a while when I found this one going for a pretty nice price. When I noticed the sorry mess of mismatched parts I had a chat with Håkan about it. It certainly did not leave his shop in that shape.

Turns out that the sellers late father had used m49B ammunition (surplus submachinegun ammo) and blown a few parts, replacing them on his own.
So now it is a Renovation Project of mine.
It looks very nice though.
