Just to add to the discussions concerning Bletchley Park and Enigma, the Americans did actually play a part in the whole business, as the National Cash Register company was the only manufacturer that could actually produce the 'Bombes' (devices used to decrypt Shark Enigma transmissions) in a great enough quality and quantity during the war. (They had a whole building staffed by their equivelent of WRNs full of them. Over 100 of the machines if I recall correctly - Bletchley Park could only manage around 18).
They also managed to capture an intact Enigma (4 rotor version) nearer the end of the war. I think this was when they captured U-505 which is preserved in the Chicago museum of science to this day.

But Hollywood still decided to portray the facts all wrong! :lol:

As for engines, you just can't beat a Rolls Royce Merlin powering by. :D

/\/\I stand corrected re. Enigma.
I guess a RR Gryphon is right up there with the Merlin :D

Probably got a slightly higher ceiling than the Merlin - we had a Gryph-engined Spitfire over the town on Saturday, it was wonderful!

The RR Griffon was from a different family of engines to the Merlin line. It displaced 36.7 litres against the Merlin's 27 litres but was only slightly larger externally, apparently. Griffons remain in service with the RAF (according to Wikipedia) in the last airworthy Avro Shackleton and in the Battle of Britain Memorial Flight. 8)

I too love the sound of large-capacity aero engines - both the V12s and the large air-cooled radials. I have never knowingly heard a Napier Sabre X24 engine run but imagine that would sound incredible too. :wink: The Napier Sabre, though, had some longevity issues, which in the field proved to be not overly helpful.

This is the one: Napier Sabre aero engine. It was indeed used in Hawker Tempests and Typhoons. :D

Forgive me if I'm wrong, but I thought that the Hawker Typhoon and the Tempest used the Bristol Centaurus engine, and the later Fury used a Pratt & Witney, or a Wright Cyclone engine?

Not sure where the Sabre came in...

It turns out that different variants of the Hawker Tempest used the Napier Sabre and the Bristol Centaurus engines! :? Two completely different layouts of engine. So we were both right! :?

EDIT - the Hawker Typhoon only used the Napier engine.

Not sure if it is still around, but many moons ago I used to see a vintage Bentley powered by a Napier engine at some of the VSCC race meetings that my father took me to. That's quite a lump to put in a car, even something as big as a Bentley! I bet the driver had plenty of hair on his chest! :D

IIRC the Napier Railton still holds the outer circuit record at Brooklands. When I was in uniform in Acton I met and old bloke who worked at the Napier Aero Engine factory in Acton Vale. He still carried his works ID with him 30 years after he left!

Ahh. The Napier-Railton. 8) 8) A wonderful old land speed record car, built for John Cobb. :mrgreen: One of my favourite cars. I had the pleasure of seeing it up close and personal at the Brighton Speed Trials almost two years ago. I was surprised at how emotional I came over! :lol: There is a track test of it (and there is only one) in one of the current editions of the classic car mags. It has a 12-cylinder Napier Lion aero-engine arranged in three banks of four cylinders.

There's a feature on the Napier Railton in this month's C&SC mag - IIRC they took it to Montlrey in France where the banking is still useable :D BTW that's where an Imp was run continuously for 24 hours once upon a time.

I've also seen this up close - it resides in BridgeNorth Motor museum in Shropshire (great museum to visit), and was parked in company with a type 57 Bugatti, Frazer Nash BMW and a genuine Shelby 427 Cobra amongst other delights!

TBH, I found the Silverstone Classic disappointing this year.

One of the best parts of the event was always wandering around the paddock and looking at the cars that have just raced - or are just about to - and all within easy walking distance. As a result of the new pit lane being constructed, they have now split the paddock into two, and accessing the main paddock area means getting a bus, which is fine - except for the queues of well over 100 people at every bus stop. So you'd have to wait over an hour to do the same - and presumably the wait on the way back is similar. We didn't bother - we were bored of queuing after fighting with traffic in Silverstone village, in the car park, when buying tickets, and when trying to get in.

Then there's the fact that the banking on the inside of Copse (which was always a good place to watch from) was covered with Jaguars. Not even rare or classic Jaguars, but commonplace stuff that was less than 20 years old. Another good place to watch from - just the other side of the bridge by Luffield - doesn't exist any more. It seems that they don't want you spectating from anywhere other than a (rather crowded) grandstand now.

And much as I love E-Types, once you've seen 50, you've seen them all. Apparently there were a thousand of them there this year. I understand the reason - and it was impressive seeing the sheer quantity of them - but seeing yet another E-Type round every corner got a little boring after a while.

Sorry for the negative post, but having enjoyed it so much in the past - and commented about it on here - I felt that I should point out that the character of the event has changed. A lot. There just wasn't the same atmosphere, the same excitement, as in previous years.

Last year we stayed until about 6pm, and were reluctant to leave then. This year we left at 4.30. I doubt we'll be going back.

At least the Imp is a little more exclusive, cant remember the last corner I saw one round.

James, you're right. It's not quite what it was in the Coys days and the access to the south paddock is way too restricted. They will be building a footbridge over the new pit straight ready for F1 in 2013. One thing we miss is the bike races together with what used to be a huge VMCC display. The racing was good on the whole, however, and as we have season passes we spend a lot of time there. The highlights for me were Group C and the gig on saturday evening. Wishbone Ash and 10CC were excellent and Suzi Quattro put on a good show...even if she can't quite hit the high notes these days :D
