#51/53/54: destroy!!
SOP is that Ministers decide to exercise the Break Clause. That sets (maybe 90 days) to rundown expenditure to zero, so on the day of Break, most persons booking to the job are fired and rundown their Notice. Contractors produce a list of kit, complete, incomplete and submit to (then MoA) for Disposal Instructions. MoA circulated these lists to Uncle Tom Cobley, as a chance to get good stuff at scrap price. (So here) BAC, BSEL, Ferranti could bid for anything from end-items to raw material - and they did; and others could bid for end items if they could see some purpose - and they did: MoA's Lectronics & GW branches took on various black boxes into concept development programmes which led on to many good things.
No one put in a bid for bespoke kit - complete/incomplete airframes, Special to Type Jigs & Tools, BOl.22Rs, Cumulus APU, because it was...bespoke. So MoA's Disposal Instructions were to scrap, and to terminate Contractors' space and succour charges NOW!
SOP. Somehow 2 airframes, various kit -B.Ol, Martin Baker, Cumulus, survived and are to be seen in Museums, or popping up on E-Bay. Ministers don't get involved with such things. Junk.
