I joined to learn more about Mausers and begin my search to eventually purchase a 98K. I inherited a few Mauser rifles that I believe were custom made in the 60's for my great-uncle that was a Colonel in the USAF. Can't say I know much about them, as he never spoke of the rifles to me. They appear to be Mauser 66 models. Maybe some of you can help me out with the identification.
