Austin Healey 100S Prototype 1954 For Sale

Unique opportunity to aquire a very special Austin Healey 100S Prototype / Mille Miglia 1954 tribute car!

the purpose of the project was to build and recreate a 100S prototype car in the exact specification as entered in the mille miglia 1954. A tribute to the three OON-Austin Healey prototype or special test cars that ran in the MM in 1954. The original cars still exist, albeit in 100S production configuration.
The three cars with OON registrations were fitted with the 100S engine incorporating angle-faced cylinder heads, David Brown S430 four-speed gearboxes, 16-inch Dunlop peg-drive solid wheels and four-wheel disc brakes. The bodies were in alloy, finished in a metallic pale green as were the subframes. The three OON cars were entered for the 1954 Mille Miglia, but in the GT class as it was thought that running in the sports car category against the Ferraris and Maseratis would prove futile. Fitted with full height windscreens, sidescreens and Universal Lamination hardtops, the cars were entered as AustinHealey 100GTs.
For homologation reasons this didn't find favour with The Italian organisers, but the DHMC team wasn't advised until they arrived in Italy. The three cars were stripped of the screens and hardtops and re-entered in the sports car category. Drivers were Louis Chiron and Lance Macklin who were both driving solo while the third was driven by Tommy Wisdom and Mort Morris-Goodall (no551). Their earlier form with the standard 100 grille and finished in metallic green ceased to exist long ago

About the 100S Mille Miglia car (no 551):
The car in question started his life as a standard Australian delivered 100 that was owned by a Austin-Healey club member during the 1970s. It was involved in an accident and wasn't repaired, but parked under a big pine tree and covered by a tarpaulin. It sat there for over 30 years until Steve Pike bought it, knowing that one day an interesting project would come up. The british heritage certificate states that the car was painted spruce green with green trim and green hood.
Steve Pike of Bacchus Marsh, Australia, one of the leading 100S Specialists built the car during 2014/ 2015. Open the bonnet of the car you will clearly see that it's all 100S. The engine block is from the 100. It was modified to take a 100S cylinder head which was one of a batch of new heads cast in Melbourne. These heads were as fitted to the special test cars/ prototype 100S with an angle face on the inlet/ exhaust while the production 100S had a straight-faced head. Similarly the special manifolds were also cast along with the extractors and of course during the process the engine was fully rebuilt to the original specifications. The gearbox is a David Brown S430 four-speed as original and mated to a bellhousing that we had cast. An alloy 100S oil cooler was also cast and used, plus a Marston alloy radiator made to the same configuration as was used during the 1950s."
Most of the parts used in the car are not fitted to the standard 100 and in some cases the production 100S. So quite a few were made new, while the alloy panels came from AH Spares in the UK. No 551 even has a competition wiring harness copied from NOJ 393 and made by Vintage Wiring Harness in Melbourne.
Only the platform from the 100 donor car was used and on to that was riveted all new alloy sub-frames and floors. The front and rear shrouds were used, but the guards, doors, bonnet and boot lid were all replaced with alloy. The sub-frames were slightly different to those on the production 100S as those of the prototype cars didn't had the same pressings. The light metallic green colour is the same as the Docker paint used in the 1950s. The suspension is all straightforward and the diff is the four-stud as with the 100S with the 2. 92:1, ratio. The brakes are discs all round and are copied from those fitted to the 100S. the callipers, piston housings and rotors as well as the hubs for the peg drive wheels were made to the prototype specification. The Dunlop 16-inch magnesium peg drive wheels were supplied by a manufacturer in the UK and fitted with Avon tyres instead of Dunlop racing tyres as the car was used on the road.
Finished in 2015 the car did it's first race at the Phillip Island Festival of Motor Sport in 2016. Shipped to Switzerland in june 2016 the car was quickly entered in the Historic Hillclimb race of Walzenhausen. Since it's completition the 100S Prototype Mille Miglia tribute car was displayed on shows like Annual Healey Meeting in Melbourne or British Car Meeting in Morges. This 100S prototype car was also featered in the US- and Australian Healey Magazine.
This is a straight and sound car. a real eyeturner in very good conditions. the car was regularly checked and always well maintained.
Exact specifications on request. incl. FIA Papers
