British No.7 Mk I/L Bayonet – M47A (BSA Shirley) Manufacture – Sten Mk V & Lee-Enfield No.4 Compatible – Original WWII/Post-War Production

This is an original British No.7 Mk I/L bayonet, manufactured by M47A (BSA Shirley) — one of the most desirable and collectible makers of the No.7 series. Produced in the late WWII to early post-war period (1945–1948), the No.7 Mk I/L is one of the rarest and most unique bayonets in the entire British small-arms system.

Designed as a dual-purpose bayonet, the No.7 Mk I features a rotating socket that allows it to mount on both the Sten Mk V submachine gun and the Lee-Enfield No.4 rifle. This unusual hybrid design was short-lived due to high production cost and limited battlefield practicality, resulting in relatively low overall numbers and strong collector interest today.

Historical Significance

The No.7 Mk I/L was produced in relatively small numbers compared to other British bayonets. Its dual-role capability and complex construction make it a standout collector piece, especially examples from BSA Shirley, which are among the most sought-after manufacturers.
