No.4 Mk.I (Cruciform) Bayonet

Availability: Out of stock


This is an original Singer Machine Company Mk.I cruciform bayonet. The bayonet is in very good condition. It appears that the bayonet has been refinished at some time after WW.II. The markings on the socket faint. The scabbard is also in very good condition


The replacement of the P'07 bayonet was considered towards the end of WWI. The cost, and not having the need to dismount cavalry would have been at the forefront of this thought. During the 1930s, with the trials of the No.1 Mk.VI and then the No.4 Mk.I rifles the decision was made to adopt a spike, socket bayonet. From the trials, a cruciform blade was decided upon. Later simplified to the Mk.II with the rounded spike during WWII. The No 4 Mk I bayonet was exclusively produced by Singer who produced only 75,000 of them.

The Mk.I bayonets, as far as I can tell, were never segregated from the later Mk.II and Mk.II* bayonets and many would have been destroyed during WWII or soon after.
