Spanish Mauser as in made in Spain at the Spanish Federal Arsenals (Oviedo or SanteFe (sp's?)
,,or is it a '1893 Spanish Mauser made for Spain in Germany at Loewe/Berlin.
I might pay $100 for the German mfg'rd hardware,,maybe,,,for a project or just a shooter if it hadn't been reblued or wood inlayed.
But not for the Spanish mfg item.
But that's just me..
1922 mfg yr I'd guess it was a Spanish mfg'r and not a German made piece.
FWIW,,Many of the Spanish mfg'r 93's were converted to the FR-7 and FR-8 carbines by the Spanish Gov't to fire the 7.62 CETME cartridge.
AFAIK, the 7.62 CETME is dimentionally the same as the 7.62NATO,,but loaded down considerably in pressure.
The bolt carbines were to be used for training and secondary issue for the CETME frontline issue rifle itself.
I don't know if it's true, but from what I've been told by 'experts', the FR-7 is safe with CETME loads only,,the FR-8 is ok with 7.62 NATO.
loads.
It doesn't sound as if the little carbine you're looking at is one of these FR conversions (sights were altered in the conversions), but I thought it worth mentioning.
Cut down military pre-98 Mausers generally have little value past truck gun status,,especially the 'Spanish' Mauser. Of the two above,,the licensed version actually made in Spain even less.
Cut down stock, inlays, reblued metal all really put the rifle in the bubba grade, though still a usable shooter for the right price no doubt.
It's a good idea to check headspace on these. They can be grossly excessive expeccially on the Spanish made rifles. Plus mixed parts are not uncommon, especially the bolt.
Though the other pre-98 Mausers are virtually the same, A Swede 94 or 96 would get $100 easily in that condition just because of it's heritage really.
A Chilean 95 might as it has (sort of) a 3rd safety lug with the bolt handle notch in the receiver and is looked upon as being safer than the 93 version.
The Argentine 91 is the same except for the straight line feed that extends the magazine below the stockline. Some are used for gunsmith projects converting to small dia bodied cartridges as the straightline feed is more easily adaptable than the staggered feed of the others.
7x57 is great cartridge for sure. Ammo is readily available loaded or as components.
I make 7x57 from 30-06 military brass. It's a reform and trim operation. Some say it's more work than necessary, but I've plenty of brass and it's not that much work to do.
Just some thoughts & things to look for.
