A wooden model of Tallboy (Medium) Bomb 32cm, raised on a mahogany stand with brass plaque marked Tallboy (Medium) 12,000 LB. 1/20 scale. The Tallboy was the first bomb Wallis designed after the success of the bouncing bomb. The bomb was so large, there were no aircraft capable of lifting it to its optimal altitude but it could be dropped from a lower height and would enter the earth at near supersonic speed, penetrating to a depth of up to 20m before exploding. The Tallboy was used on strategic German targets such as V-2 rocket launch sites, the V-3 supergun bunker, submarine pens and the battleship Tirpitz, as well as large civil constructions such as viaducts and bridges  £400-600
