No. 69 Grenade
The No. 69 Grenade was a bakelite percussion hand grenade introduced into British service in Dec 1940 and produced until Nov 1946.
Two different Marks were produced; the Mark I was widely used, the Mark II was experimental and never adopted.
Grenades with red filling rings or red 'X's painted over a green band indicated the grenade was filled with Amatol explosive. For grenades filled with Baratol, "BAR" was stenciled in white on a green band. For grenades filled with Lyddite, "LYD" was stenciled in white.
The Mark II was larger, and some versions had fragmentation sleeves added, but these trial models were found to be inferior to existing grenades.
