No.85 MkI

This British HEAT rifle grenade was similar in shape and size to the US M9A1 grenade.
Its base fuze was the main difference, together with the stand-off distance.
The fuze designation was No.430 Mk1 or Mk2 which was, unlike the american fuze, armed by the igniting propelling charge (diaphragm).
