Hello, I'm fairly new here and have the German Mauser disease pretty bad. Found a sporterized one a couple days ago and would like to get some of your opinions on it. I've read about them in a couple of books but haven't run across one until now. It is a 1917 dated Simson and co. Gew98, but in K98 configuration with Nazi eagle proof marks on the barrel and receiver, all matching serial nos. and a few different waffenamts on several parts. It is in an old fajen or bishop sporter stock and looks to have been reblued a long time ago, the bore looks almost like new, whoever had it before removed the entire rear sight, sleeve and all. I love to rescue these old sporters and to study them, and try to restore them to their correct original configuration. Any info or opinions on this will be appreciated also any info on removing and replacing the front sight, so I can install a new rear sight sleeve will help, thanks in advance.
