1916 Erfurt "Failure to ****"

[ChuckM]

Thanks so much for your reply. When doing as you asked, it immediately caused the Firing Pin Spring Guide to shoot out of the Breech Block. It is the face of the Breech Block where it shows signs of damage, what I would call "peening" of the metal and the locking tab channel inside appears very shallow and worn. I have included some pics of those parts. The sear bar that you refer to, I assume, is what is referred to as the Trigger Bar on the schematic? I don't know how to remove that. I am guessing it involves prying up the Trigger Bar Spring somehow? If you could give me some addnl instruction on that I will remove it and post some pics. Thanks for all of your help. C.

PS - The Trigger Bar is one of the few parts on the gun that doesn't have matching S/N's so my guess is that it was replaced at least once before. C.
