I have several 7x57 Mausers but two are kinda special. The first is a custom sporter that's been stuck at the 50% completion level for a decade or more. Unfortunately I don't have any pictures of it but it's got nice custom metalwork on a 1910 Mex action and a beautiful English walnut stock,.........just need to find a qualified craftsman(and the money)to have it finished up. Have a matching gun in .257 Improved(also 1910 Mex and 50% complete).
Another 7x57 has some interesting history with it, but the only pics I have for it were taken some time during the last century with my first digital camera,......a 3 deca-pixel Sony. Too poor to post, but here they are anyway,..........
Several above have mentioned the use of the 7x57 Mauser during the Boer war. Well, this is one of those. I picked it up cheap at a gunshow many years ago because someone had 'bubba'd up' the stock with carvings. Actually, I think it was bubba'd by two someones,........
JJ WEBB is carved into the right side of the buttstock. I assume this is the Brit soldier who captured it. At the Magwell is carved Z A R,.......Zud African Republic. Forward of that on the forearm is the name of the Boer soldier(I forget the name and can't make it out in the pics). All these carvings are fairly typical of the Boer Mausers. There's a very interesting article written by the late Jack Lott in the 1975 Guns And Ammo Annual concerning the weapons used in the Boer War and one rifle prominently displayed is a carved up Mauser Carbine just like mine,...........in fact the two serials are separated by about a dozen numbers iirc.
I seriously need to dig this one out and get some better pictures taken.
