BOUGAINVILLE:tinysmile_shy_t:
It has no longitudinal serrations as with Types "91 and 97", but has five transverse depressions. Onone side, fitted top and bottom, are two metal rings which could be used for carrying a number of grenades attached to the person, or for anchoring grenade for use as a booby trap.
It was filled with 39.5 grams of granular TNT and the fuze gave a delay of approximately 5.5 seconds.
OPERATION:
To remove the lead cover, the cover thumb release catch at the side must be depressed. The cover then screws off in one and a half turns, exposing the firing string. When the firing string is pulled, it draws a friction igniter between pieces of match composition and ignites it. The match in turn ignites the five and a half second delay train which initiatesthe detonator, thus setting off the main charge.
