The Merlin was use in loads of stuff, Mosquitoes, Halifax, Wellingtons, etc. around forty types in all and also the Packard copy used in the MTB's.
Used a derivative on the Centurion MBT and Centarv IIRC...Meteor?

Ahh yes, forgot all about the tank engines - The Meteor was indeed based on the Merlin although chopped and changed a bit.

I heard, many years ago when I was working for Shell, that when they were opening up the oilfields in Alaska they used Ex Canadian air force Merlins to run the generators. Apparently they were so cheap and available they just ran them till they dropped then fitted a new one.

(I also remember seeing crated Ex RAF Tiger Moths being sold in Exchange and Mart for £600. :))

The flat Lycoming on the Soux /Bell 47G was allegedly designed for pumping water but was too damned noisy.

I still love to hear one, they were "the" archetypal helicopter of the day. The Blue Eagles used to visit occasionally....History now

:) Who remembers the Whirlybirds ?. I had the flat Lycoming engine on my Piper PA-28, although only the four cylinder.

MTB's used the superb Packard V12 4M-2500 marine engine, which was a unique pre-WW2 Packard designed marine engine, and other than being a V12 bore no relation to the Merlin engine whatsoever.

Off Norfolk coast, I'd say odds on it will be ex-RAF (most likely bomber force in that location, so Lanc or Halifax, but Mosquito is also a possibility in that area) or an ex-USAAC P-51.

Yea, just about, and skippy!!

You know I cant even remember if it was a flat 4 or 6...pretty sure it was a 6, with the G4 having a turbo charger. The bloody things could barely hover with a crew of 2 in the heat!!

Its sad but inevitable when you look back and see what's gone.

I was trying out a powerpoint on the cadets on monday about the history of the Kings Royal Hussars. It struck me that even in my lifetime the forces has been decimated. I suppose that is a good thing, but it shook me when I looked at the number of regiments I was aware of when I was serving that have amalgamated or disbanded.

Same with aircraft, I had no idea the Sea kings had gone totally, I thought it was just the HAR2s with the RAF

Sorry, this has sod all to do with the thread, juts meandering as usual :squirrel:

Superb, but unfortunately petrol. I've always wondered why we and the Americans lagged so far behind the Germans in diesel engine design and adoption. A failure that must have led to many deaths in tanks and MTB's due to the combustability of petrol.

We had no real need for it pre-war, and petrol was king in the USA, so diesel market there must have been tiny so fuel companies were not even bothering I suspect. The Germans spotted the need because it was convinced about the effectiveness of their U-Boats, and thus diesel engines were perfect for that.....as well as having no oil reserves, I guess, diesel gave another advantage.

And yes, RN 'Dog Boat' crews were well aware of the risks of sailing around in a wooden boat containing a 5000 gal AVGAS tank!! I have that first hand as one of my Uncles was regular RN, joining pre-war, and serving through WW2 in the Med on the Dog Boats as a gunner on the Oerlikon....so I grew up through childhood on tales of those Packards etc., roaring him around the Med.
