WW1 BRITISH No12 Mk1 (HAIRBRUSH) GRENADE

This No12 Mk1 commonly known as a Hairbrush grenade is almost certainly a reproduction not original.

In use the small lever is straightened from the safety position and the pin is pulled. This releases a plunger held back by a spring which fires a percussion cap igniting the delay fuse, at this point the unit is thrown.

Your comments:

• The 11th field coy RE report in the war diaries that the hair brush weighed 5lb in comparison with jam tin which weighed 2lb. The jam tin being preferred as easier to throw.
