TYPE I: The case, parallel-sided, is constructed of cast steel terminating in a shallow dome at the base. The nose of the bomb, which is thicker, is tapped to accommodate the fuze and has two holes bored transversely for grub screws to secure the fuze.
TYPE II: The bomb is constructed with a double casing of drawn steel. The space between the inner and outer shells is closely packed with steel pellets set in concrete. The pellets are cubes, having sides of about 7mm. The over-all thickness of the bomb case is about 0.6 in. The outer shell is 2mm thick and has a nose piece integral with it. It is closed at the base by a steel disk over which the shell is folded. The inner shell is 3-mm thick and terminates at the base in the form of a truncated cone. The two shells are scarf jointed together just behind the nose. Four steel supports are welded between the inner and outer walls of the nose and act as spacers.
SD 10FRZ: This French bomb is very similar to the German Type I. The tail is constructed of four steel pressings welded together, each pressing forming a segment of the tail cone and one fin. The tail is secured by four rivets and four indentations.

For types I & II a long exploder system is used when the filling is TNT. This consists of a normal gaine; one penthrite pellet, two compressed TNT pellets and one phosphorus pellet. The main filling terminated about 1.9 inches from the nose and so permits the use of the AZC 10 (Hut) * (3) fuze. The Z (66) fuze's gaine fits only partway in the exploder pocket.
When the main filling is 60/40 amatol, a short exploder system is used with a a normal gaine and one penthrite pellet. The bomb is filled to within 1.2 inches of the nose so the AZC 10 (Hut) * (3) fuze cannot be used.
SUSPENSION: Seventeen of these bombs are carried in the AB-250-2 container.
COLOR AND MARKINGS: Body and tail unit are olive green. Body has D10A13 or 14 stencilled in black on it. Tail has 4 red stripes down cone between fins. Type II has 1/2 inch red stripes on outer edge of tail fins.
