CARTRIDGE CASE: Not known.
FUZE: Nose, Hbgr.Z. 35 K; Base, Bd.Z. 35 K.
REMARKS:
Slightly streamlined base. Ballistic cap threaded to body of projectile.

Projectile has rifled design which takes the form of 12 longitudinal inclined splines (incli-nation 5° (approximate)). These are approximately 60 mm apart and are probably inten-ded to engage in the rifling of the gun. The splines do nor appear to be machined from the main projectile body but are constructed separately on strips of steel which are then fitted into grooves cut in the projectile body. These grooves are undercut to procedure secure attachment. To the rear is a copper or bimetallic driving band, the probable func-tion of which is to act as a gas seal.
