Man, that's a beautiful rifle. Gorgeous. I recently (ok, several months ago) bought a 1893 Spanish Mauser made in 1901 from a work colleague. Unfortunately, it's been MEGA bubba'd. The stock is ugly and sporterized. The barrel is turned down to 18" and is hourglass shaped. I know it's not bulged, as I've slugged the bore and there are no "loose" spots. Just whoever turned the barrel down on the lathe must have been really drunk that day.
I still haven't fired it. I've always wanted a 7x57. I think it's one of the greatest all time do-it-all calibers. Something special about it. Since it's in such rough shape, I've also though about getting it rebarreled to .257 Roberts, another all-time great caliber that I've always wanted. I think it would be cost-prohibitive though, so I may just keep it as-is and wicked-ugly for now and just fire the thing. Who knows, it may be a tack driver?
