M31 German Canteen Cup Aluminium

The M31 German Canteen Cup was a standard-issue item made of aluminum, introduced in 1931 alongside the M31 canteen. It was used throughout World War II, with its production evolving as the war progressed and aluminum was needed for other purposes. While the cup was originally an aluminum part of the M31 canteen set, the material and other components like straps and covers were altered over time due to material shortages, leading to later variants.
