BACKGROUND: Development of the M34 heavy mortar began in 1932 and was based on the design of the WWI Stokes mortar. In 1934 the Rheinmetall munitions firm presented the M34 heavy mortar to the OKH, Oberkommando des Heeres, (Army High Command), who approved and accepted it as the primary infantry battalion fire support weapon. The M34 heavy mortar was manned by a three man crew and fired an 8cm caliber shell to a maximum effective range of 2400 meters.

PHYSICAL DESCRIPTION: A 10cm x 28.5cm x 37cm light weight wooden case with dove tail corners, hinged lid, and spring latch. The lid is marked "MUN. S. GRW34". The carrying case is complete with rack insert. The wood shows typical usage and wear for such an item. The case was designed to contain three shells for the 8cm M34 Heavy Mortar.
