That Bucciali at Retromobile is a repop on a Cord L29 chassis... The U16 chassis was never bodied. The only car that I no of with a U engine that ran was the Simca U8 proto, never made it to production.
The blue car is a Talbot, manufacturer of high end cars and successful race cars before WWII and pos after
No cycle cars there but gorgeous and out of reach.

 

Thanks for the information - we had a big debate at the show as to whether it was original or a copy.

 

Where there's a will there's a way:

 

Bugatti Type 45:

 

was unsure about Bugatti applying their U to a car; very sceptical about one being started by a crank handle ...

 

great shot - getting close !

 

I learned something today thanks Nedd.
@Blackjack There was a board on the wall behind the Bucciali explaining all this ... in french

 

Well that's pretty close. I may well have been thinking of the Birkin photo but I recall seeing a more impressive photo in a publication as a kid - possibly the weekly publication called 'On Four Wheels'. It had a huge impression on me at the time and accentuated the diminutive 7 against the Bentley that looks like a green (b&w) wall behind it.

Sorry for being off topic here

 

Ahhh - there's my problem...

 

Can anyone give me more info on this Austin7 special? I would really like more photos of it in order to build a cyclekart based on it.
Thanks,

 

Well, studying the pictures, its got a straight I-beam front axle with dropped kingpin ends. the axle itself is suspended from beneath (that's pretty kewl!) by a transverse buggy spring, and the frioction shocks are also mounted transversely just a bit above the axle.

looks as thoguh the original austin rear live axle has been converted to run sprockets on the axle flanges, and then chain drive to the rear wheels on a straight beam axle. (the suspension method is not shown, but since A7 specials were limited to using the original A7 chassis, I am assuming that the rear suspension is the stock Austin 1/4 eliptic leafs.

that help?

 

Right, it looks like he just turned the spring shackles around to put the axle above the frame mount. Still uses the stock friction shock. Center of gravity is really low. For a cyclekart it would be great; alum. body with no compound curves.

 

That method of suspending an Austin Seven front axle is actually quite common on single-seat racing specials.

Edit:





Many axles are tubular, though, as may be seen.

 

Something I have often wondered about on construction, especially on racing vehicles is seen in the foreground of the first picture. It is the rear of another car, but the bracketry for holding the rear spring shackles seems to be a rod that passes through the frame and out to provide a pivot point for the shackle. I've seen this on front suspensions in early Indy cars too. If it truly is a rod - is it made from steel something like 'drill rod' for strength? Anyone have knowledge about this set-up? Thanks - sorry, not trying to hi-jack thread, but saw the picture and it triggered the question - and the answer might be helpful for anyone else thinking of building their own car in the future.

If you are referring to this picture, it looks like a rear chassis cross piece, probably of steel tube to act as the rear attach point for the spring. Just sort of a cross member that is wider than the chassis.

 

Basically a rear spreader bar for the frame horns that doubles as a outboard pivot allowing the shackels to pivot up, lowering the car and giving a wider spring base.

 

I'd like to see a video of this car/picture in action. Any ideas, anybody?

Thanks for that info Ned. I had thought that may be the case. I had not thought about aftermarket tubular axles though. I see the last pic shows the Austin axle being used. I googled Austin 7 specials and got an eye full. That car probably is responsible for more specials than any other make in the UK. Amazing little car.

 

The Seven was in a way the British Model T.

 

yep but if you have ever driven one you know it is more akin to a cycle car than a tractor.

How well does this front suspension handle?

the car in your attached pic is a front-drive Miller speedway car, either a 122 or 91, circa 1925-1929.

 

I'd expect it all depends on how the axle is located laterally.

 

Is the chain drive used to facilitate independent suspension under the rules requiring A7 chassis/drivetrain? or is there some other reason?

 

Probably about like a model A. I can't imagine the tall, narrow 7 handled very well but as a special they must have been much better.

 

It's a good way to reduce unsprung weight.

 

I love the mechanical tach on the steering column.

 

I think also the ability to change the gearing would be good especially given the different hill climb courses we have in the uk
