DESCRIPTION: |
|
The pistol consists of an aluminum body threaded at the bottom to screw into the float, and a steel striker which rests on a creep spring and is prevented from rotating by a longitudinal guide key moving in a groove in the striker body. A safety pin passes through the pistol and striker bodies. On the upper end of the striker are threads for the vane collar and the vanes, and to these is attached a vane cup to protect the threads of the striker. A transit clip fits between the vane collar and the pistol body. |
|
OPERATION: |
|
The transit clip is removed when the pistol is put in the float and the safety pin when the float is placed in the dropping gear. The vanes and vane collar rotate up and off leaving the striker riding on its creep spring. On impact the spring is overcome and the sharp firing pin hits the detonator. |
|
REMARKS: |
|
(1) This pistol is similar to the obsolete No. 5B except; (a) the body is aluminum, (b) it has no body threads, (c) the arming vanes are secured to the vane collar by screws, (d) the 5B has a guide screw engaging the striker groove, rather than a long key. |
|
(2) The No. 23 Mk I is the same as the No. 23 except that it has a black plastic body. |
