1956 Austin-Healey 100M Roadster Registration no. UXG 881 Chassis no. BN2-L/232493 Engine no. 1B/214994M (not original)
Its accompanying BMIHT Certificate shows that this Austin-Healey 100M was despatched on 16th June 1956 to the USA and confirms that it left the factory as a genuine 100M (or 'Le Mans') model. The car was located for the vendor at The Healey Werks of Lawton, Iowa. It was shipped back to the UK in 2002 and converted from left- to right-hand drive when restored by MPH Ltd of Blockley, the rebuild being completed in June 2004. MPH completely stripped the Healey and restored it from the chassis upwards. The original shade of Reno Red was found beneath the right-hand drive steering column aperture blanking plate, which ensured the colour was correct when repainted.
As the car was for road use and not intended for competition, it was fitted with Girling M16 disc brakes and a 3.9:1 rear axle ratio, the original 4.1:1 crown wheel and pinion being severely worn. Although the engine block is not original, the carburettors are correct for the 100M as are the other features including the anti-roll bar and louvred bonnet. The air box clearance notch alteration was as expected, but there was no kink in the diagonal bracing where the access was sometimes made for the fitting the 100M camshaft. After fitting new pistons and an aluminium cylinder head from Denis Welch (with the steel-faced head gasket), the compression ratio is 8.68:1 compared to the 8.1:1 as originally stated for the 100M and 7.5:1 for the standard 100.
The car has a 140mph speedometer, which was apparently sometimes fitted to the 100M. The vacuum advance has been removed and the mechanism fixed in the distributor to ensure correct engine timing over the engine speed range as advised by Jeremy Welch. We are advised the overdrive is working as originally intended and changes down on the throttle. The throttle pedal is built up to suit the owner. The headlamps have halogen bulbs, and fuel filters have been fitted between the fuel tank and the pump, plus another before the carburettors.
The car has been fitted out to suit the vendor and has all the attributes to make it easy to drive in modern traffic without overheating the engine or driver. We are advised that it does not drag its exhaust on the ground and keeps up with motorway traffic when required. In addition to those mentioned above, the car boasts the following notable features:
Up-rated springs to 3000 specification
Denis Welch DWR1 (100M) camshaft
Denis Welch 100M tubular side-exit exhaust system
Denis Welch carburettor heat shield and inlet extensions
Carburettors fitted with 'super dry' seals
Lightened flywheel and balanced crankshaft
Spin-on oil filter
Extensive heat insulation
Heavy-duty clutch linkage
Alternator instead of dynamo
Kenlowe thermostatic fan and large radiator
Alloy rocker cover and sump
Denis Welch split steering column
Horn and indicator switch on dash
Derrington wood-rim steering wheel
Mirrors fitted to extended windscreen pivot bolts
Rear leaf springs fitted with Polybushes
Lap and diagonal seat belts
60-spoke wire wheels shod with Michelin XAS tyres (two years old)
Records are available of all the work done in restoration and subsequently on the car, which has been regularly maintained, with any major work done by Denis Welch Motorsport or John Chatham Cars, both of whom are recognised Austin-Healey specialists. Most recently, the car was serviced at John Chatham Cars in September 2021. New 6V batteries were fitted in 2021. The car has always been garaged and in winter is stored in a Carcoon inside the garage. It is no longer submitted for annual MoT.
The car is described by the vendor as in excellent condition, but does show signs of use as one might expect. The vendor has had a great time both using and working on the car over the years, but recently poor health has made it impossible for him to drive the car regularly.
