Title: WWII AB23 Butterfly Bomb Container

On the night of 13th/14th June 1943, 3,000+ butterfly (or Sprengbombe Dickwandig or SD2) bombs were dropped by the Luftwaffe over Grimsby, Cleethorpes and Great Coates. The SD2s were not dropped individually; they were packed into AB23 containers each holding 23 'butterflies'. An electric airburst time fuze type 79 blew open the hinged AB23s and the anti-personnel SD2s spun towards the ground. Counting the empty AB23s provided a guide to the number of SD2s in the vicinity.

This modern photograph of a totally inert AB23 with a type 79A fuze was recently acquired along with the copyright.
