This shell has a pointed and solid head having a radius of about 1½ calibres. The walls are tapered and threaded internally at the base to take a base percussion fuze. Exter-nally the shell is fitted with a ballistic cap welded on and a groove is formed near the base to take a copper driving band; the groove is knurled to prevent the band turning on the shell. Immediately below the driving band a small groove is formed for crimping on the cartridge case to the shell. The explosive filling is Tolite contained in a cardboard wrapping.

The weight of the shell complete with fuze and gaine is 1.73 lb.

Note. – Pieces of 37 mm nose fuzed shell have also been recovered. The dimensions and method of fixing to the case are the same as the above. No complete shell has, how-ever, yet been found.
