INFO ONLY. NOT FOR SALE. P82-11
The No. 68 was an early form of shaped charge grenade, and has some claim to have been the first High Explosive, Anti Tank (HEAT) device in use. The design of the warhead was simple and was capable of penetrating 2 inches (50 mm) of armour in 1940.
The grenade was armed by removing a pin in the tail that held the striker. The grenade was launched from a rifle cup. The simple fins gave it some stability in the air and provided the grenade impacted the target at the proper angle (90 degrees) the charge would be effective. Detonation occurred on impact when a striker in the tail of the grenade was thrown forward into the fuse.
