Model 23, Mark I (Rifle)
This grenade is nothing more than the No. 5 fitted with a rod 5¼ inches long screwed into a steel base plug which in turn screws into the bottom of the grenade. To keep the lever of the bomb in place after the pin has been pulled, a ring attachment is fixed to the rifle by means of the bayonet.
