Unpainted black steel body with a green band followed by a maroon band below the fuze. This is a simulation of standard Navy marking of H.E. projectiles which typically are pain-ted maroon over all and tipped with green.

Fuzing: Type 3 combination fuze.

Weapon in which used: Navy type 3 8-cm mortar.

Description: The body of this shell is one-piece cast-steel streamlined construction with a well machined bourrelet having five bearing surfaces. An adapter ring screws (R.H.) in-to the nose, but there is no booster cap as in Army types.

Screwed into the base of the shell body is the tail-fin assembly consistins of steel tube to house the propellant cartridge and having eighteen flash ports in six rows to pass the flash from the primary cartridge to the main propelling charge. Welded around the base of the tube are a series of twelve stabilizing tail fins. The main propelling charge is con-tained in doughnut-shaped silk bags, which are split so that they can be slipped around the propellant tube above the tail fins and over the flash ports.
