Lanchester MkI: Britain's First Emergency SMG
The Lanchester MkI was Britain's first emergency submachine gun, developed by reverse-engineering the German MP28. Initially adopted by the Royal Navy and RAF, it featured a distinctive brass magazine well and utilized SMLE rifle stocks. The MkI* variant simplified production by removing the semi-auto selector. Despite its weight and parts non-interchangeability, it served until the 1970s.
