Olle..yes that is a much better photo..It's been re finished to some extent because there used to be a big ole date heavily stamped into the front of the chamber and it's gone.
Also the underside rails etc should all be in the white..no bluing. The Germans discovered blue caused spalling of blued friction surfaces so they didn't blue a lot of the inside. Your outside rail looks like it has been blued.
