Hi,
I have a bolo mauser but it is not a typical one. serial # 42,XXX so circa 1904-5 all serial numbers match and it has the early black (bakite?) grips with a shield and stylized letters inside which also have a matching serial number(see photos). Ok, so looks nice, shoots nice, but it is in .30 luger (which seems odd) and it does not have the luger like step in the barrel by the muzzle like a typical bolo. I thought well maybe a post WW-I re-barrel, but no tell tale seams inside or out even with a magnifier. The grips are original and the grip size is a bolo with no evidence of modification. I love shooting it but as a collector would like to understand what I have. Any help is appreciated. Matt
