Stunning and textbook M31 tropical canteen in close to mint, most likely unissued condition. The canteen is a typical example with a nice webbing strap. The flask itself is marked SMM 42 indicating a factory mismatched example produced bySüddeutsche Metallwarenfabrik, Mussbachin 1942. The cup is nicely marked 7W S. Excellent tropical M31 canteen which would be very hard to upgrade!
