TMD-40 mine

The TMD-40 was a wooden-cased Soviet anti-tank blast mine used during the Second World War. The mine consisted of a rectangular wooden box which contained a detonator assembly at each end and seven 400 gram and four 200 gram blocks of explosive. The fuse assemblies consisted of a lever device, which when pressed downward by pressure pieces attached to the lid of the mine, see-sawed upward, pulling the striker retaining pin from a pull detonator. The main charge was then triggered.
