text: PB995 was sent to the Aeroplane and Armament Experimental Establishment (A&AEE) with PB592/G, a conventional B.Mk 1 built in 1944, which was to be modified to a B.MK 1 (Special). Some equipment did not need to be fitted but other items were removed, which began a period of removals and reinstatements; a conference on 25 February was necessary to sort out the confusion. The front and mid-upper turrets were to go, along with the H2S, its fairing and the TR1196 R/T set, electric lights, flare chutes, flame dampers, some of the fuel tanks, the rear turret armour, three fire axes, a toolkit and the crew ladder. The commander of 5 Group, Air Vice-Marshal Ralph Cochrane ordered that the Identification friend or foe (IFF) be got rid of in favour of the VHF Bomber Fixer. Despite bombing by day, navigation equipment was needed because of the north-west European climate; GEE and LORAN were to be carried along with high-altitude and low altitude radio altimeters. The recognition lights and some of the usual VHF equipment were to stay along with the rear guns and 6,000 rounds of ammunition. The bomb doors had to go as even the widened Tallboy bomb doors would not fit a Grand Slam and as the mid-upper gunner and wireless operator were redundant, the crew was cut to five men.
