M31 canteen marked HWSD 42

Heavily used mid war production M31 canteen. The aluminium flask and the cover are marked HWSD 42 which indicates production by H.W.Schmidt, Metallwarenfabrik, Döbeln in 1942. The brownish cup is nicely marked with the 3 letter code gfc which indicates production by Julius Posselt, Gablonz an der Neisse, Reichsgau Sudetenland. The cup is MPD marked with the material S which indicates the usage of Phenolic resin (bakelite) with sawdust as the filler material. Sadly the cup is heavily damaged and repaired as can be seen on the pictures!
