The Star of David does not mean Israel lie service, the Spanish Civil War mauser has it. The original Mauser manufactures in Germany were Jewish , before Hitler was born, so no one would have thought anything about it. I’ve seen them on Turkish rifles too. The 95s were converted to nato 7.62 with a chamber insert that some say are unsafe.
Found this about the subject-http://castboolits.gunloads.com/showthread.php?348171-Star-of-David-on-Mauser
Nonetheless the mausers made for Israel after the creation of the nation had the star on the top of the receiver, I have one and from what I found on Wiki about 1/3 made for Israel in 7.62 had the star from what i read.
Long ago in Shotgun News there were Belgian Mausers, originally 7.65, rechambered to .308. The bore was in the .311 range and the accuracy reflected it. But for a cheap truck/deer gun -?- More recently there was imported a herd of Spanish 93's that had been redone to .308. Article in Guns and Ammo I think reported that HP White labs had tested them and the conversions were late made model 93 pattern, Spain used it until 1943 I think, and were adequate. Value? I paid $38.00 for my first Mauser in '06. Got ammo for $0.03 per (mil surplus). Those days are long gone now. Luck.
It would have to be either rebore or rebarrel 7x57 is 284 diam. and the 762 is 308 diam but of course most would know this. seems to be a lot of mouser barrels floating around. another question what were the 98?
Deacon - The Model 98's were chambered to 7.92x57mm aka as the 8mm Mauser. I have one in our family that was a bring back from the war.

When you allow a lie to go unchallenged, it becomes the truth.
