Hey i have on layaway and k98 from a local gun store, it has the mauser banner on it, and a gear looking emblem stamped on the side of the reciever but NO serial number, or date of when it was made. it has a straight bolt in it, but u can tell its not original and is made to have a bent bolt. upon measuring, inspecting and looking at everything on this rifle top to bottom, it has got to be a K98, but no serial number or date on it?
