Title: Butterfly Bomb Type 67 Fuze
Author: P. M. Fenwick

Another of the three different fuze types which were used by the Luftwaffe for their 'famous' butterfly bomb (SD2) raid on Grimsby. This time it's the clockwork '67' fuze which could be adjusted to detonate the bomb at intervals between 5 and 30 minutes after arming whilst dropping. The variability of these fuzes added to the terror caused to the Grimsby area in June 1943. (See 'Grimsby's Most Horrific Night'.)

This cut fuze clearly shows what is essentially a clock/watch inside which was probably made by a former cuckoo-clock factory in the Black Forest.
