Today whilst visiting the Fenland and West Norfolk Aviation Museum with my 'personal guide' Richard Mason, a very nice and knowledgeable person, we came across this Coffman Starter exhibit, having read this thread and not knowing what they look like, I snapped a photo, Richard then showed me a second unit fitted to a recovered engine, which I 'think' was a merlin ???? I am sure you kind people will recognise the engine from what little is on view in my photo ????
