I can’t see any of your picks. Is this a military or commercial Mauser?
Okay, I just read that and it sounds like a military model. From your description I would say that the safety broke off and the and the cut out…plunger…whatever you want to call it is in bolt lock position. The cocking piece will be on it so, it’s going to be under a bit of tension. Take out the safety. Pull back on the cocking piece with whatever is handy to relieve the tension and point the muzzle to the sky and shake and bang around on the rifle enough for it to fall out. You might have to try to get in the hole for the safety and try to turn it…with non tension on it, of course.
There is a recess in the back of the boot that mates to the end of the safety arm.
