I would look at other alternatives instead of selling a rifle my Granddad and my Dad owned. That's a family heirloom, a very nice one at that, and I believe you will regret it if you choose to sell.

If you really want to find out the most you can about your rifle, go the German Gun Collectors Forum and post pictures of ALL markings on the piece, both above and below the wood. Those boys have forgotten more about Mausers than most folks have ever known.
