I wonder if any former BEA/BA people would be able to tell me anything about this ? I came across it quite recently,and can only assume that it was passed to me by his widow when my friend and neighbour, Tony Fisher,died a few years ago.Tony worked for BOAC/BA all his working life,apart from National Service,first as a radio/radar engineer,before finishing his career as managerof the B737 sim. at Cranebank. Apologies,title should have read TOOL CHECK rather than key check.
