I'm sorry....

OK - on the back of a Krieghoff's frame, just below the toggle cut-out, there is a small "semi-circular" dark area that was hardened at the factory (where the toggle â??notchâ? strikes the frame at full recoil). That dark semi-circle is commonly referred to as a "thumbprint" by Krieg collectors - and you can see the "thumbprint" quite readily on un-restored Krieghoff Lugers (and some "good" restorations that mimic that same "thumbprint" by flame harding the metal in that area again).

Best to you..!
