I was about to clean up a modded and rusty old Mauser but thought I should check with some folks that know more about these old guns before I start wire brushing on it. It's pretty rough and doesn't have the original stock so I think the tube magazine has been cut? The rear sight is missing too.
Should I clean it up as a family keepsake or fully restore it or clean it oil it and leave it alone?
Edit: One interesting thing I noticed is the curved bolt handle w/ square knob. I can't find any pics on the web of another one like this, is it likely a modification?
