I have a brochure put out by the Austin Motor company Longbridge, Birmingham along with Donald Healey motor company The cape, warwick which is publication number 113. This brochure titled Austin Healey Hundred ( model BN 1 ) SPECIAL EQUIPMENT AND TUNING INSTRUCTIONS, is 18 page brochure and has sections A to I covering modifications that the factory made available to Austin Healey 100 owners through the factory and dealers. Section A dealing with engine states " To enable the engine performance to be increased a kit has been produced. this kit was fitted to the Austin Healey cars that completed the Lemans 24 hour race in 1953." The engine modification kit is designated;
LE MANS ENGINE MODIFICATION KIT, PART NO P 280.
Power increased from 90 Bhp to 110 bhp with the fitting of this 25 piece engine kit and other modifications recomended by the factory brochure which included suspension, axle, brakes etc. Section I also gives list of available extra equipment through the factory which included the Le mans tune up kit ( P 280 ) Aero screens, 15 and 25 gallon fuel tanks with straps, Alfin brake drums, race type negative camber rear springs, race type Anti roll bar, close ratio over drive, race type silencer, front shock absorbers, crown wheel and peion and a special speedometer to go with the crown wheel and penion.
This clearly indicates that the factory did approve the use of a Le mans kit with the blessings of Donal Healey and made it available through the dealers and from the factory direct. Thus it is evident that some of these kits were installed by the delaers at the request of customers and of their own accord to prove the performance of these cars. the adage Drive to work on weekdays and go to the race track during the week end may have become true with these type of modifications done to the Healey 100. The truth is that most of these mods may not have been done before these cars were sold but after the cars were acquired by the first owners. Furthur all the modifications recomended by the factory may not have been done to each car and it is possible that partial mods were done. So a dealer modified car is one fitted with the Le mans kit supplied by the factory and although not any different from the kit being fitted at the factory it is not the same. The real difference is that the 640 or so cars done at the factory were recorded as factory produced and got recorded as such and have special value because of that and most of them carry numbers stamped on each panel to identify assembly of these panels on the correct cars, badges and other unique features which could not be duplicated by the dealers.
The current issue and discussion relates to value of the original cars produced at the factory and the value that should be placed on the cars that were fitted with the same modifications by the dealer or the owner who could buy this same kit and do it at home. How many of these kits were produced and sold is not known, so there may be a lot of these modified cars around and more will appear as time goes on. Instead of saying it is a car modified by a owner, now every car is identified as a dealer modified car which gives it a little more credence when it comes to re sale. The question is how much were these cars modified to come close to a Le Mans car ? . My Brochure has photos and information about what accessories were made available to modify these cars and they were very extensive and I am sure the mods were done by knowledgable people in stages. The question is if only partly modified are they still designated as having a le mans kit installed in the car ? One of the major things that was not offered in the kit was the louvered hood and most of the dealer modified cars did this on their own so they may not be all looking the same or have the same fin count unless they copied the factory installed hood. Also the dealer modified cars now are also stamping the steel panels with id numbers like they did on the 640 odd factory cars to give it a more authenticity. For all these reasons i think a factory le mans car is not the same as a dealer modified car and should be considered as such. At the inception it was performance and proving the breed and driving and enjoying a good sports car to work or the track. Now it is all about getting the best price for your over restored car. So this discussion will go on forever between the factory Lemans car owners and the dealer modified car owners.
Just thought I will let everyone know about this information.
