WW1 Mills no. 36 hand grenade with 1918 dated rifle base plate.
The No. 36 Mk. 1 was first introduced in May 1918.[8] It used the No. 23 Mk III body with a new-style plug. Mostly made of iron, it was drilled and threaded for attaching a metal disk called a gas check to fire the grenade from a cup discharger (Burns) mounted on a rifle's muzzle and launched using a ballistite blank cartridge.
