Black bakelite canteen cup marked 46/S

Beautiful black bakelite canteen cup in a stunning condition without any damages. The cup is nicely marked with an MPD code which was typical for period produced bakelite items. The MPD code 46/S Indicates production by Erich Wippermann, Halver i. Westfalen. and that the used material is Phenolic resin (bakelite) with sawdust as the filler material. Nice cup to complete a canteen or a display!
