Sir - the letters Ms stand for Mehrschuess - multiple shot - and Es for Einzelschuess - single shot. This rifle appears to have a five-round magazine in front of the trigger guard - this is a Ms.

The sights would certainly have been fitted to this rifle originally - the screw-cutting may have been done along with a reblue to give it its present appearance although te location of the rear sight can clearly be seen in your first image. Please measure the aol of the barrel - it should be 650mm/25.75". You should also be able to find the metal composition code on the barrel - Ch.22 or Ch.23 - this will also help us to date it. The stock was originally a deep gloss finish, BTW.
I have not seen any .22 Mauser rifle of that period that was made just for the .22 Short cartridge, BTW, but I'm prepared to be educated on this point. You can help us by giving us details of ALL the markings on this gun - you should be able to find .22lfb if it is actually .22LR - or .22Kurz for .22 short, as well as the more usual BUG marks and others such as DRGM. You might even find [Not English make] and the usual British proof-marks - especially as it has been modified by screw-cutting.
