Pre war M31 canteen marked SMM 34

Very interesting non-matching canteen with all pre war parts and 1934 dated flask. Sadly the parts are not matching but the canteen is found as is and seems to be untouched. The rarest part is the flask itself which is marked SMM 34 which indicates production by Süddeutsche Metallwarenfabrik, Mussbach in 1934(!). The cup and strap are dated 37 and 36 and made by different makers as shown on the pictures. This is a sadly mismatching canteen which is quite usual, but still a very interesting one with early pre war dated parts! Early parts of standard Wehrmacht equipment is almost impossible to find and very desirable!
