Thanks to Pete I discovered what model Mauser I have. I'm still looking into it but based on no markings it narrows it down to Model 1916. Comments are still welcomed.
Info on the Unmarked 1916:
Unmarked Model 1916 rifles have 22" barrels, tangent leaf sights, a thumb cut and gas escape hole in left side of the receiver
I bought this rifle on the fly based on the action mocks a Mauser (the firing pin spins off etc). Anyway As I broke it down there were no common stamps that I could see. All I can go by is a serial number. As far as looks that's the part that I need the most help on. I broke it down today and took lots of pics. I attached a slideshow to photobucket. Questions please ask.
Total length 44"
