Reproduction of the spanner wrench used to remove and adjust the buffer assembly and zeroing the MGZ sights on the heavy MG mounts (MG Lafette). The 13mm spanners fit the nuts of the buffer assembly, while the 11mm open end wrench is used to adjust the concentric screws on the block mount for the optics. This would have been carried in the gunner's pouch by troops manning HMG's.
Marked "hey 41".
Blackened steel.
