Years ago, I found an 1895 Spanish Mauser sporter on the C&R rack of the LGS.
Bolt was missing. $50.00 price tag.
I bought it.
Asked the old guy behind the counter if he knew what type of Mauser it was?
He said if they knew that, it wouldn't be fifty dollars!
Have since bought a replacement bolt. Need to headspace it.
Still chambered in 7x57mm.
