| Description: |
|---|
| The bomb consists of a nose casting, fitted with a striker assembly and a tail cone which constitutes a container for the filling, and is fitted with a central tube for a detonator buster. The nose casting is made of iron, internally threaded at the rear to receive the spigot portion of a central plug which closes the forward end of the tail cone. The interior of the nose is filled with lead, and has a clearance hole for the striker rod. The striker is secured by a cotter pin (removed when loaded), a safety pin spring-loaded outward, and a shear wire through the guide bush. |
| Use: |
|---|
| Included in this section are five sizes of prac¬tice bombs. These are the only ones specifically designed for that purpose, although there are currently in use several practice bombs which arc merely service bombs inert-loaded with sane, water, or a chalk time solution. The standard practice bombs generally emit smoke as a spotting charge to indicate bombing accuracy. Standard practice bombs arc painted white over-all with two light green bands painted around the center of the tail. Inertloaded service bombs used as practice arc painted black. Practice bombs containing an exploder have a red band painted around the rear portion of the body. |
| Functioning: |
|---|
| The sheet-metal tail cone, constituting the container for the filling, is closed at the rear by a conical steel tail plug and at the forward end by a central plug which screws into the rear of the nose casting. A tapped hole is provided in the central plug for filling purposes. Secured to the tail plug is a tail tube having four fins, which carry a cylindrical strut. The tail tube is closed at the rear by a cap. |
