I have a double trigger Mauser sporter that my father bought back in the 80's for 25 bucks . It is in really good condition with a really nice sporter stock, scope and still has about 95% bluing on the reciver and barrel. Wish I had pics but my brother has it at his house and has been dealing with "the problems" for abour two years now and its time to take it back. Now about the problems and questions, the rifle came with no bolt seems the first owner took it out and misplaced it 10 yrs before it even crossed my pops ("He knew somebody who knew about stuff like that" , the guy move away)and too make matters worse the caliber is also unknown and the rifle is unmarked. So, how hard would it be to find a bolt for it and find out what caliber it is or would it be safer to rebarrel? Also how expensive are good bolts? I once got told by a gunsmith that it was not worth the trouble but when you look at her I can see myself taking a whitetail with her. I could make it into a lamp

but, it's too nice and my girlfriend would never let me put it the living room!
Another quick question would it be a good idea to try the bolt of my 1912 chiean mauser to check if its a standard large ring action? No live ammo will be used in any way and I have not tried the "drop test" with live ammo to check for caliber, that too unsafe in my book.
