BRITISH No69 BAKELITE HAND GRENADE, 1941

Manufactured from 1940 to 1944 by De La Rue Plastics out of Bakelite moulding with a No 247 All-ways fuze.

Your comments:

• Missing from the specimen shown here is a length of tape with a pin at one end and a tape at the other.
  
  When the grenade is thrown, the tape unwinds and withdraws the pin from the all ways fuse.
  
  The all ways fuse comprises a metal ball trapped between two concave cones, one of which has freedom to move when the pin is withdrawn.
  
  Upon any impact, the kinetic energy of the metal ball forces the concave cones apart causing the striker mounted on one of them to strike the detonator and the grenade is thus exploded.
