I'm hoping that someone will be able to help with some questions I have. I was given a model 1893 in 38-55 and am trying to determine its age. The serial number starts with an A followed by four digits and i can't seem to find any records of serial #s starting with an A. The barrel is marked "for black powder", which i believe puts it somewhere between 1905-1912. The confusing part is that i read that this barrel would make this a model 1893b from 1905 onward but it is not marked this way.
