This is a very rare British No4 Mk1 Cruciform bayonet that was manufactured by Singer Manufacturing.  This bayonet is in original condition and is still packed in the original grease with wax paper. I have removed the wax paper around the markings to show that it has the proper “SM” Singer maker mark.

This bayonet is one of the rarest No4 type bayonets to find.  This beautiful blade will make an excellent addition to your British Enfield collection.
