There looks to be a set of marks on the left side of the tube just forward of the receiver, which may be the bullet weight. But odd that a mm stamped Suhl made rifle doesn't have the bullet weight. Interesting >>U<< on the top of the frame. Too, interesting double witness marks. Also interesting is the rear sight?

The stamps on the left side of the barrel forward of the receiver is "560" - that number doesn't match up with any other numbers. Perhaps a serial number or item number from the retailer. As to the rear sight, its absolutely original from when the rifle was built. I have several other pre-war German Mausers that have have original Lyman rear sites. I also have several pre-war German catalogs that show Lyman rear sight and Lyman Scope options. Also, the stock wood cut for the rear sight clearance has "age-period-patina" just like the rest of the stock's woodwork. It is also interesting that the rear sight filler block on the barrel is original and not later added. And finally, there is a small radius cut in the Lyman sight's base block to allow clearance for use of a stripper clip. You can see this in the 4th and 10th pictures.
