No. 77 Mk. I smoke grenade
No. 77 Mk. II smoke grenade

The No. 77 Smoke Grenade was used by the Commonwealth Forces in WW2. The basic function of the two variants was the same. The grenade used the "Allways" impact fuze meaning that as soon as the grenade hit the ground, the fuze would detonate and the filler would scatter and ignite as soon as it touched the air. The body of the grenade is made of tinplate. The two variants used different fillers: the Mk. 1 used white phosphorus, the Mk. 2 used titanium tetrachloride. Although the grenade was initially designed as a smoke grenade, the Mk. 1's white phosphorus filler also made it extremely dangerous to enemy infantry as it had an incendiary effect. It was withdrawn from service because the body of the grenade had problems with corrosion leading to dangerous situations.

The main visible difference between the two variants is the base plate - the Mk. 1 uses a coned base plate, whereas the Mk.2 uses a flat base plate.
