Made of steel, enameled. There may be a paper label inside. Production date not set. A volume of 350 ml.
Mug fits comfortably in the "kidney" mess-tin and sits tight in it, not dangling, pressed by the lid.
The mug was included in the set of World War II soldier's equipment along with a spoon. It was worn either in a backpack/bag or outside, pulled by the strap by the handle. The remains of these mugs can often be found on the ground on battlefields in Russia: their pieces are well preserved thanks to the enamel.
