Background

It was a simple idea done well, which is a good sign any car is likely to become a classic. Take a beefy engine from a large manufacturer and build it into a pretty two-seat sporting body, producing genuine 100mph performance.

The first ones, built from 1953 to ’55 and known as BN1 in Healey code-speak, used the 4-cylinder 2660cc Austin A90 engine and a gearbox arrangement with the very low first fear blanked off, so that second became first, leaving only two more gears – but with an overdrive you could use in second and top, giving five ratios in all.

That was sorted out during 1955 when the BN2 came along with a proper four-speed ’box, still with overdrive on the top two ratios. Slightly larger front wheel arches and optional two-tone paint were the only obvious visual changes. There were two hot versions: the rare and now priceless 100S, which was a race-prepped derivative, and the fast road version called the 100M, which boosted power from 90bhp to 110bhp, gaining stiffer front suspension, louvres and a bonnet belt.

The last four-cylinder Healeys were made in 1956, with the new 100-6 coming in late in the year to start the second generation of Big Healeys with six-cylinder engines and a pointed oval grill shape rather than the wide fan-shape of the original 100s.

A word about those looks. For some reason we can all name famous Italian stylists – Bertone, Pininfarina, Giugiaro, Michelotti – and yet their British counterparts remain obscure, even when they’ve designed a shape as faultless as the Healey 100/4. So have a good look at this extraordinarily pretty, well balanced car, and give an appreciative nod to Gerry Coker.

Overview

1956 Austin-Healey 100M Roadster

Registration no. UXG 881

Chassis no. BN2-L/232493

Engine no. 1B/214994M (not original)

• Genuine factory-built 100M 'Le Mans' model

• Exported new to the USA

• Professionally restore by MPH in the early 2000s

• Converted from left- to right-hand drive

• Extensively upgraded

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.

The seller tells us 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. The owner says it doesn’t drag its exhaust on the ground and keeps up with motorway traffic when required. In addition to those mentioned above, the car boasts some notable features:

Exterior

These include:

Uprated 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)

This Healey looks like a really cherished classic. The paintwork gleams, the brightwork dazzles and everything is just as it should be. The louvered bonnet with its leather strap are 100M special fitments. It’s a gorgeous example of a de marque.

Interior

It’s not just the outside of the car that Gerry Coker got spot on – the interior is equally simple and stunning. The red leather bucket seats and quilted leather transmission tunnel cover add a real air of class, and the simple dash layout has never really been bettered.

This later car has the four speed gearbox with added overdrive operating on the top two ratios, effectively giving six forward gears.

Mechanical

The simple four cylinder OHV engine in this car has been improved with an alloy cylinder head replacing the cast iron original, allowing it to run a higher compression ratio, improving performance, and saving weight in the process.

The car’s underside looks totally sound, as you’d expect from a Healey restored by specialists, and molly coddled since.

History

This 100M’s accompanying British Motor Industry Heritage Trust Certificate shows that it 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.

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.

The car is described by the vendor as in excellent condition. 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. He says:

‘I had a job away from home which paid well and as it was running up to my retirement I decided to buy a classic car. The Austin Healey was British, had no wood in its construction, was ‘large’ where a Midget is ‘small’. And it was powerful and fast enough for regular use. I sought a 100M if I could find one.

‘I have suffered poor health since I had a heart bypass operation in January 2020 and have been unable to drive the car any distance as a result. and I can no longer work on it. Its mileage has been negligible since and the car does not do well to stand idle. I would like to think that it will be moved on to someone who will enjoy using it. It was never an investment, it was always for fun both looking after, to improve drivability and of course driving.

‘It came back to the UK complete with a lot of rust and some bullet holes! In 2002 it was the only 100M that we could find at the time. The car was fully restored on its return from the USA, the restoration took two years. After having to be mended after a fire which took place on its first run around the route routinely used by new Healeys built at the Cape Works it went straight off for the first of three visits to Classic Le Mans. It took part in the Parade Des Pilotes on the Friday before the race in 2006.

‘The reason the carburettor overflows are not piped into the cold air box is because the float valves were kept open by debris and pumped fuel into the air box where it ignited due to a spit back caused by an ignition fault. Fuel filters have since been fitted before the fuel pump and before the carburettors in order to stop any dirt getting into the float chambers.

‘However my wife was made nervous by the fire and we decided to direct any overflow to ground from then on. The original overflow pipes are in the spares box and the risk is virtually nil that the same thing could re-occur, but just in case there are two fire extinguishers in the car which have never had to be used of course! The record of spending is in the documents box as is the photographic record of the restoration.

‘The car is in great condition after use over my 20 years of ownership during which it has been kept dry in winter in a Carcoon inside a garage and has been regularly serviced. There are one or two blemishes as you might expect as the car has been used up until three years ago.

‘A record of all the work done on the car is in the documents file. I have recently had the radiator re-cored after it sprung a leak due to the mounting of the Kenlowe fan – something that has been corrected during a thorough service at John Chatham Cars in September 2021. The batteries have been replaced since and the car is running beautifully and everything works as it should. I have always reacted to a problem to keep the car functioning 100%.

There is a list of the modifications that have been made in the documents with the car, all of which improve its usability. Good front disc brakes, side exhaust outlet to stop the tailpipe hitting the ground, large radiator and Kenlowe fan to stop engine overheating, Michelin XAS radial tyres, and heat insulation make it comfortable even on a hot day, the 60 spoke wheels prevent the problem of 48 spoke wheels breaking up and were a period option.

‘The engine that came back with the car is not original and is in fact older. Engine components that have changed include the pistons, the cylinder head, the camshaft, the rocker and sump covers and the exhaust. The oil pipe to the oil pump and the oil gauge have been replaced with braided pipes to minimise risk of breaking and leakage. A spin-on oil filter, an alternator, quieter five bladed fan, and a split steering column.

‘There is a 3.9:1 ratio back axle. The vacuum advance was removed and the advance mechanism locked to ensure correct ignition timing over the full range of engine revs. That was done on the advice of a Jeremy Welch at Denis Welch Motors who provided most of the parts and work on the car before we moved to Bristol, and it cured a problem with pinking and overrun after switching off. The carburettors are original – there are no ticklers so that the pressure in the air box could be equalised by the overflow tubes.

‘All Austin Healeys are special. We made sure that the original paint colours were used and over my years of ownership all the work done on the car has made it better than the original specification. It can be an everyday car – as long as it is not raining too hard! The hood leaks rain in along the top of the windscreen – every 100 is the same in that respect. It is a great drive and the extra power of the Le Mans version with the raised compression ratio gives quite a kick!

If the car is looked after properly it will look after you. It has proved reliable and usable for me.’

Summary

A gorgeous example of a rare 100M, that’s been cherished, maintained regardless of cost and enjoyed. It’s now ready for its next custodian.
