I am not sure what it is and I am wanting any information anyone has on it. I think it is a 1908 or a 1903 but I have no idea what the difference is. The interesting thing is what I think the serial number is. It is a four didget number on the left side of the frame -- 93XX. Is this a collectors gun with a high valu or is it one that I can put a few hundred rounds a year through?
