My experience with magnesium wheels is that they break when you clip a curb (or anything else, for that matter). Magnesium is a fairly brittle material - though light weight. They do make the most wonderful sparks, however, when scraped along a barrier.

It very much depends on the alloy and design. For example the Minilites I use on my 1977 Group B Porsche 911 RSR, will stand up to the most amazing amount of abuse. I have seen people finish stages with no tyre on the wheel for the last few miles and the Minilite all still in one bit. They are certainly far stronger than the Fuchs wheels, where I had a rim failure in 1976 on a Kremer 911 2.6RSR, when landing after a hump back bridge on the Circuit of Ireland. The car spun one and a half times between stone walls without a scratch, which given that the walls were only a car length apart, you would have thought was impossible, but I have never used Fuchs since. Magnesium wheels do suffer from corrosion and age hardening and I am always horrified to see people racing on original magnesium wheels, e.g. Lotus "wobblies". There was a guy on a rally in the USA a couple of years ago, who was proudly telling everyone that the Hallibrand mag alloys on his 1953 C4-R Cunningham were original. I asked him if he had a death wish and suggested he put the originals on display in his garage and fitted identical replicas, which are available. Even Minilites which have a stove enamelled finish to prevent corrosion, realistically should be replaced at a maximum of 10 years. You can have them annealed, which supposedly reverses age hardening but I would not bet my life on that.

Could it be a 1954-55 Chrysler GS-1, which appeared with various bodies on it, mostly by Ghia.

PS if it is, I note it has been "Frenchified" with Marchal headlights.

Dunk,

 

Quite correct and commonly known as the Leon Bollée Tricar. This one is owned by a friend, who takes it on the London to Brighton every year. I don't think he has ever made it past Crawley. It has become a bit more reliable since the burner for the hot tube ignition (none of these new-fangled spark plugs) has been converted from petrol to bottled gas. However as the flame is next to the carburettor, a gust of wind in the wrong direction still sets the carburettor on fire. Last year the soldered brass sheet crankcase for the open crank split and allowed the drip feed oil to the splash lubricated big end to leak out faster than it was being replaced. The big end became red hot and parted company from the con-rod, shooting across the road. It was not difficult to find, as it had set the verge on fire. The gears run in the open below the drivers legs, controlled by twisting the grip on long handle sticking up on the driver's LHS and the clutch by pulling this lever backwards or forwards. A totally looney tunes device. Makes our 1904 Panhard et Levassor seem ordinary and safe.

Wilson that's a very entertaining story. 

 

Here's the next puzzle ready but cannot give many clues. Suffice to say it's one of approx. 52 made; maybe No. 11; I forgot to take a photo of the brass nameplate showing its actual production number; it's a competition car and it's road legal; the owner drove it to the Kettering Vintage Rally and Steam Fayre last weekend. The owner also owns and drives a vintage Bentley he bought over 60 years ago when he earned just £15 per month … and also owns a Chevrolet Corvette Stingray … plus a few others too! He told me the mystery car is capable of over 90mph and has competed in hill climbs - but given its early history can probably reach speeds in excess of that. The biggest problem when driving the car is coping with the boy racers who drive alongside and also cut in front as they attempt to take photos because they've never witnessed such a vehicle on English roads. The engine is approx. 4 litres and sounds wonderful - but it's not easy to start. The owner took over 10 minutes to start the engine (hand cranking) but after judicious adjustment of choke and probably the advance and retard? lever it suddenly burst into life.

 

I do not now the exact model but maybe someone will recognise it.

 

I do know the actual make and type … but it's possible that the type is also the model.

 

Note it's R.H.D. :)

 

So … looking for the actual manufacturer, and the type, and the approximate year of manufacture plus or minus 2 or 3 years.

Two more photos added . The gear change mechanism and position has been re-engineered; originally it was in the centre of the car where it fouled the driver's leg … so the previous owner arranged repositioning to the RHS. Note the large water bottle … the radiator required topping up before the engine started … engine has a constant small drip water leak. 

 

Another clue is that the fuel requires hand pumping … there is a centre-mounted hand operated fuel pump between the two bucket seats.

Forgot to mention that the car has rear brakes only … no front brakes … but this fact may not have hindered its competition performance to any great degree … which could be a clue to its identity. 

 

And note the tax disc showing that it's road legal.

 

And forgot to mention the owner also has a 1947 HRG 1500 sports car … he's quite an enthusiast.
