Gray overall with a green band forward of a blue band on the nose.
A cast steel nose is attached by a continuous circumferential weld and 16 plug welds to a longitudinally welded tubular steel body. A tail cone, is attached to a collar by 36 screws. The collar is held in the base of the bomb body by a single row of 16 plug welds.
The tail is constructed in two sections, the first section has eight 1/4 inch sheet steel fins welded to the tail cone and supported by seven steel struts. The second section consists of eight plywood fins in steel frames supported at their inner edges by a metal cylinder 4 inches in diameter and on their outer edges by seven steel struts. The second section is attached to the first by bolted steel plates on each of the eight fins. Apparently the wooden tail section is designed to come off on water impact.
