This shell is a modification of the 29 lb HE shell used with the 5 inch barrage rocket. The modifications consist of a threaded adapter screwed to the spigot on the base plate of the shell. The adapter is externally threaded to screw into the shell ring of the 3 inch rocket motor. Further modification of the shell includes alteration of the exploder pocket to receive the larger booster assembly of the Fuze No. 721. The shell is painted buff overall, with a 1/2 inch red band painted around the nose portion of the shell and a 1-in. green band painted around the shell body. On this band the initials of the type of filling used are stenciled in black.
No information about functioning.
