A non-functioning safety lever on a Mauser action is an A1 danger signal.
This sounds like Bubba, who may have
1) fudged together bits from different types of Mauser actions. Like, for instance, installing a striker with incorrect length.
2) FUBARed the sear/cocking piece/bolt sleeve interaction in a misguided attempt to lighten the trigger pull.
In both cases, the rifle is in a possibly dangerous state, and the cure could be expensive.
Whatever you do,
DO NOT TRY TO FIRE IT.
The FIRST thing required for diagnosis in such a case is PHOTOS of all the bits!
