1891 Argentine made in Germany won't fire

[AlaskanUser]

I'll take it apart again and get pics and measurements when I get home tonight...

Sounds like there is something funny going on here. The 1891 Argentine Mauser has a two position safety, and shouldn't need a 1/4" spacer to unscrew. I've got about 6 3/16" firing pin length here, very slight protrusion at the rear. Nickel is inserted for disassembly. Does this look like yours?

Will post pics much later tonight or tomorrow. Thanks, guys. I'm pretty good with most guns but have zero experience with this one. Even if it's a bastardized assembly I really want to get it working for the memory of my Dad.

Hmm, wondering if the OP's bolt is made up of mixed parts? Maybe a M'93/95 bolt shroud/firing pin assy screwed into an M '91 bolt body? If that's even possible...
OP, does your bolt shroud have the Argentine "shaking hands" inspectors stamp on the left side like in the second pic above? It should be on the cocking piece and firing pin too, IIRC.
