AE work hardened??

Hi,

Well, contrary to what many believe, the Parabellum pistol was never a 'rush job'. Some corners were cut when it came to the exterior finishing, you see some rougher and more visible tool marks on the outside, but that's about it.

When the barrel and receiver have been cold blued, I would be careful. Chances are that someone messed with the barrel, and perhaps heated the receiver to get it out, compromising the metal in that area. The barrel should be relatively soft, the receiver was hardened, as were parts of the frame (frame ear ramps).

DWM and Mauser used a flame hardening technique, it wasn't until the 1970s that induction heating was introduced as an alternative.

Hopefully our machine shop wizards can come up wit more detailed info.

ps: "Hello Tim"
