Tom, I also have a large collection of Mauser parts, barrels, sights and alot of other parts, I'm sure I could help you also if you could provide a picture of the sights that you need. If you are having trouble identifying your model 98, I might suggest useing a book titled "Mauser Rifles of tne World" by a gentleman named Robert Ball. If you don't have the book, it may be available in your local library. Please respond to my e-mail: rterps@comcast.net By the way, the original sights were secured by soldering them to the barrel. Keep in mind that the new barrel will have to be chambered after it is secured to the action. I would encourage you to have a gunsmith install and chamber your barrel. They have the necessary equipment to do the job safely and securely. Please let me know if I can help.
Sincerely,
Charles R. Erps
