Re XV147 & XV148
XV147 was purchased by BAE Systems in 1993, it was indeed sectioned at Farnborough with the Port wing and Fuselage from the nose to Rear Pressure Bulkhead taken to the BAE Warton site in Lancahire in support of what became the MRA4 project.
The interiour was fully stripped and converted to MRA4 standard with cockpit and mission system areas completed.
The wing center-box was removed to develop the technique used on all subsequent airframes to under go MRA4 conversion.
The nose radome was dug up from the golf course at Woodford and fitted to the aircraft. The last use for the airframe was to act as crew egress trials before it was finally cut up and road hauled off site 17/03/03 (The same day it was announced to chop the MRA4 from a 21 aircraft build down to only 9).
The wing was also used in support of the MRA4 project but was disposed of earlier than the fuselage because the all new wing of the MRA4 negated any benefit.
XV148 The fuselage and wings were used as fatigue rig test pieces in support of mk1r & MR2P, and have long since been scrapped, the only portion to remain is the cockpit section which is currently down South owned by the Author of the AirBritain publication covering the history of the Comet - Mike
