I bet that caused some panic in the Engineering Department - 'And where the very Devil do you think I'm going to put it Sir?'. They were more polite in those days.
Pye did some CT/Octal jiggery-pockery during that period, but very rapidly settled on the B8As - not necesarilly the best choice in retrospect.
