RAF Bomb Armourers Tool No7 Mk I

This is the first example of this scarce instrument that we have had here. It is marked on the grip 'Gauge Cavity Detr. A/C Bomb no 7 Mk I', dated 3/41 and also marked C.E.Co. It is also stamped with GN 12 contained within a circle. These tools were used in the arming sheds prior to fitting the fuses and detonators by the armourers to check the cavity in the nose of bombs and also pistol in tail to make sure correct fuse is fitted prior to the ordinance being armed and loaded prior to an 'Op.' Made from solid brass (we assume to avoid sparks) and this would have formed an essential part of an armourer kit. We can supply a period image of the tool in use on request. Measures 8" (20 cm)
