DESCRIPTION |
|
The pistol consists of a body (1) in which a longitudinal hole is bored. The striker (4) fits into this hole and is held in place by a .16 inch aluminum shear wire (5). The striker (4) has a mushroom-shaped head (9) which is internally threaded to take the arming spindle (3). The vane cap (8) is keyed to the arming spindle. The cap (8) and striker head (9) have small anti-binding lugs (7). Holes are drilled through the cap to allow seating of the safety pin (6). The pistol is held in the bomb by a band locking spring (2), the usual British method. |
|
OPERATION |
|
The arming wire is withdrawn when the bomb is released, thus allowing the vanes to rotate, raising the vane cap (8) and unscrewing the arming spindle (3). The vane cap and screw fall free. On impact the striker (4) is forced inward breaking the shear wire (5) and striking the percussion cap. |

REMARKS |
The Mk II variation differs only in that spring-loaded metal safe-ty blocks are lodged between the striker head and the fuze body, under the vane cap. This is an additional safety feature. |
