I was involved in setting up the Airframe bays for the Nimrod AEW3 at Waddo, many years ago. One item we received, brand new, was an OF4 based static hydraulic test rig. On opening the adaptor cupboard on the back of the rig, three trays of adapters were found, all in waxed and greased paper labelled Lancaster, Halifax, and Stirling as I recall.
