While we're on the subject of correcting things....
AFAIK no Lancaster was re-engined with Griffons. This may relate to a batch of ex-Shackleton Griffon 57 engines that were converted to drive a single prop for use in Spitfires. That did involve a different gearbox, and the idle setup became a bit of a compromise between the rather high idle setting of the Griffon 57 and the much lower setting that the original Spitfire Griffons had. I know that the Rolls-Royce operated Spitfire XIX used one of these engines, don't know if that is still the case.
