So IMO those are pics of a 1895 Spanish Carbine-1916 Pattern that was re-arsenaled to 7.62 CETME( basically an under-powered 308).
And it looks to be in great shape. It's not an 1893 due to the strip clip loading cut out in the receiver.
I have both; an 1893 long rifle (no cut out) and a 1895 /1916 pattern carbine, both in 7x57 mauser and I only load to 40,000-45,000 PSI which is about 33,000 - 37,000 CUP.
These loads offer plenty of killing power for deer, antelope, and black bear and with 110 to 130 grn Ballistic Tips great for varmints too.
Well, that's my take on it!
