Mauser Mount Mismatch - Replacing the Rear Base - 1940 Gustloff Werke Kar 98k

I recently purchased a sporterized 98 Mauser - it turns out that it had Weaver Bases for a small-ring Mauser installed! I replaced the #55 rear base with the proper #45 - which required some clearancing. It’s a shame that the rifle was sporterized - it’s a nice example of a 337 Gustloff with matching numbers, other than the cocking piece and firing pin. I’m guessing those may have been replaced when the Timney Trigger was installed. I haven’t decided what I’ll do with the rifle yet - the next step is to take it to the range! I’ll evaluate afterward. 1940 337 Gustloff Werke Karabiner 98 k Ru Ruhrstahl AG barrel blank Geco finished barrel --- Devine Life Society by Jesse Gallagher
