"In all my years as a soldier, I have never seen men fight so hard." - SS Obergruppenfuhrer Wilhelm Bittrich - Arnhem
I would say that this is a war time after assembled piece the front frame war time made of or with the tool
because the hinge and the pin the late war period ,but the hook not original Souval piece.
on the core is small swastika but the number is LDO period
I think this the piece not wartime period.but this only my opinion
I'm looking for EK II 1939: B.H.Mayer: A and B core,mm L/18 and schinkel type ,,,EK1 Round-3 with Deschler frame and Friedrich Sedlatzek pin and SB variant
