I have found a "Standard modell Mauser" action only, with all numbers matching.
The only negative I can see on it, is three drilled holes one the side, underneath the Standard-Modell writing. These holes have been filled. Still not sure how they look on the inside of the action. Waiting on photos.
I am wondering what is this boards opinion on these actions to build upon? I am thinking a 7x57, with a custom built peep sight on the rear bridge. No drilling and tapping for scope!
