Thank you for your input.
I just want to know for sure whether the bolt was re-stamped to match by someone other than the German army.
And if so I would like to know how one can tell.
Also what would account for the trigger guard and floor plate being replaced?
Here is information regarding the Waa stamps.
Here is what I have found.
77 is marked on the: Receiver (next to the 3 swastikas); bolt stop (top); Rear of the bolt; under the bolt handle; under the safety;
Waa623 is marked on the: Barrel (right side); stock; muzzle band;
Waa497 is marked on the butt plate.
There are NO import marks.
Hope this helps.
