ZB-53

The ZB-53 was a machine gun used by the Czechoslovak army designated TK vz. 37 ("TK" means "těžký kulomet", heavy machine gun. "vz" means "vzor", Model) and later used by German forces during World War II as the MG 37(t).

It was an belt-fed, air-cooled weapon that served both the infantry support and vehicle weapons roles. The British adopted a version of the ZB-53 as the Besa machine gun for their armoured forces.
