Well, I've found the markings. They're VERY vague. With a light they are hardly recogniseable.
Cant really tell what it says. Lóóks like 43 but that cant be. Must be 46.
Does a Stutzen have its own model on it? Like '46 stutzen' or 46ST?
Dont think it has been reblued though. It actually should háve a reblue

Do all model 46 have the holes in the plastic foresight? Or stutzen only?
