Wasn't this in the aircraft fitted with the 300series engines not the 200??
All of them. 100, 200 and 300. One of the early B1A's actually came back and landed 'cos the crew weren't aware of how bad the damage was.
After that the AEO could use his periscope to take a butcher's and assess the damage.
Incidentally, after Rolls royce took over Bristol Siddeley they wouldn't touch the Olympus engines and we were much bemused by a brass plate attached next to the data plate stating "Overhauled by the Standard Motor Co. Ltd." when they came back from overhaul. I wonder if any of the TVOC engines have that plate fitted?
(Standard Motor Co. was the company that built the RAF's favourite staff car of the 50's and 60's - the Vanguard).
