Newbie trying to enter world of milsurp

Hello all. I was recommended this forum to get help on identifying a rifle offered for trade. I've always been interested in milsurp, but always afraid of getting ripped off. Not only K98s, but also Mosins and 1903s have always interested me. Hope I can find the info I need here, thanks for having me!

Welcome aboard. A person would be hard pressed NOT to find answers on anything Mauser on this site. Fact based answers too, not shots in the dark. Punn intended.
