Interview with Michael Moenstermann, the current owner of ADU 7B, one of the original Triumph Spitfire factory works rally cars.

Michael, who lives in Germany, recently found and purchased 7B in France.  The car had been stored for a number of years in a barn and needed a complete restoration.  Michael rescued the car and sent it to Jigsaw Racing in England for body restoration work  which is currently in process.  Below is an interview I conducted with Michael about his experiences in finding and restoring this famous Triumph race car.

 

JW:)    What first got you interested in the Triumph Spitfire works race cars?

Since I was racing a MK I Spitfire I was interested in the racing history of the works Spitfires. There was (and is) not much known about them except the chapters in some of the Spitfire books and more detailed information about the technical aspects of the cars were really hard to find. The more I read and try to find information about them the more I got hooked, but the whereabouts of the cars were at this time only rumors. The only known cars at this time were ADU 4B in the US and ADU 8B in Japan.

 

JW:)  Michael, I understand that you found ADU 7B in a barn in Northern France.  How did you come to find it there?

I saw ADU 7B advertised in a British classic car magazine in 1998 by a French classic car dealer. I picked up the phone immediately, made a date, grabbed my books and some money for a down payment and drove the next day down to Lille in northern France. I saw the car, tried not to look too nervous, negotiated the price a little bit and bought it.

 

JW:)  What was the owners story of how the car came into his possession?

 I found that out later when the car was already in my garage. The car was sold after the closedown of the competitions department in 1966 to the French Triumph importer Voitures Monceau in Paris. He passed the car onto the French race driver and Triumph dealer Roger Barbara in the Lille area with the obligation to promote the car in a certain number of events. He did so and installed at some point later a GT6 engine in the car. The car was sold then into private hands at the end of the 60ties and was the last time registered in 1973. It was put in storage in the owners barn then. A French Triumph enthusiast started to search for the car in the 90ties and located the car about 1996 still in the area. The owner knew what he kept in his barn and the French enthusiast couldn’t afford to buy it. He passed the information onto the Triumph Sports six Club in the UK and a number of people came to see the car, including Graham Robson and an ex works driver. I think the more people came to see the car the more  the price went up. Finally the French classic car dealer bought it in 1996. The car was first mentioned in a British classic car magazine in 1996 and was advertised after that sometimes. The Triumph scene didn’t mentioned the car and amongst some insiders the rumor was spread this car was a replica. The source of this rumor was probably Graham Robson who stated in his Works Triumph book that ADU 7B was in the UK since the 70's. Later it proved that this car is a replica build from some works spares by a competition department member.

 

JW:)   Did you have any problems convincing him to sell it to you for a reasonable price?

No, I think I was the very last one in a long row of people who were interested in the car. I think some people went quiet about the car hoping the price would drop over the time.  But I think I paid a reasonable price.

 

JW:)  Most people only dream of encountering a find like this, what were your initial thoughts when you first saw the car?

From what I knew already from the phone I was in doubt how original the car would be and how the overall condition would be. My first thought was, yes it is the real Mc Coy, even if I couldn’t prove it at that time. I walked around it looked at every detail and could feel somehow the history of it. There were many things which reminded me of the pictures I saw in the books, like the huge petrol filler cap, the steering wheel and I was relieved that the original aluminum head was there. Without the head I wouldn’t have bought it (probably) because I knew that it was almost impossible to find one.

 

JW:)  What sort of condition was the car in when you found it?

At the first glance it looked somewhat strange. It was painted dark blue with a green bonnet and was converted to LHD. I first thought the bonnet was added later but I could see from the inside were the additional headlamp pods were cut out and replaced by an aluminum panel. The grafted in bulge made it worse but the overall condition was quite good. There were no rust holes, no signs of an accident. The bonnet and doors fits very well and the sills had the unique quick lift apertures. From underneath were only surface rust and I thought that the car didn’t run for a long time. It was obvious that the car stood for a very long time because all the hydraulics were dry and the brakes were seized. I found it interesting that there were no contact corrosion between the aluminum and steel panels. I found some cracks and dents and inside the car I spotted the original powder blue color.

JW:)  The car still had some of it's original racing equipment that came with the car.  What special equipment originally came with the car and how much of it is still missing?

The major items were all there although the original drive train was replaced by a standard unit. There came some parts with the car like the aluminum cylinder head, Weber carbs, a works gearbox and camshaft and other bits and pieces. The interior looked quite complete but all the expensive instruments like the clock and the Halda were missing. Seats, dashboard, long range aluminum petrol tank, door panels, roll bar, everything was there and seems to be in good condition. I already had the special rev counter at home (0-8000rpm dial) and found in the meantime the special clock and the Halda, the special Lucas light equipment as well as some other small unique components from the dashboard. I was able to find all the missing parts and some parts were made to order like the wiring loom. The build in headlamp pods which were cut out at some point were still in the boot and the middle section of the bonnet is now back in the proper shape.

 

JW:)   As I understand it, you reside in Germany, however the body is currently being restored by Jigsaw Racing in England.  Could you please tell us how you came to choose them for the restoration?

I met Mark from Jigsaw via the internet. He has the same passion for the works Spitfires. He is currently building a Le Mans replica for himself. He has a very good source for building and repairing aluminum panels and is taking care of every detail. England is well known for its knowledge in restoring classic cars and source for British parts so I decided right from the beginning that the delicate work should be done in the UK.

 

JW:)  Have discovered anything interesting about the car since beginning it's restoration?

Yes, I found that the chassis is of Le Mans specification. I found remains of quick lifts at the front and the rear and some other details. On the back of some parts and panels I found marked ‘ADU 7B’. The body was strengthened and modified in certain areas. The car was initially painted wedgwood blue and was painted then powder blue (which is a bit lighter than wedgwood). The cars were taken direct from the assembly line and wedgwood was the only light blue color available. I think in the competition department was then decided that the cars should wear the same competition color as the works rally TR4’s.

JW:)  How authentic are you going with the car in terms of restoring it?

As close as possible, this has grown now to an obsession. No modern upgrades or modifications will be made. I spent a lot of time with searching for pictures and information about the original specification of the car. Although some parts will be different like some internal engine parts. As the original Salisbury limited slip unit is missing I will use a Quaife unit (until I will find the proper one). I have the original Armstrong adjustable shock absorbers but they are worn out and it is very difficult to overhaul them, so I installed Koni dampers which were also used during that period. Another almost impossible to find part is the original rubber carpet used on the early Spitfires, so I will use here a later pile carpet. Most of the remaining equipment will be left as it is, even if it is not in perfect condition like the seats and door panels.

 

JW:)  I understand the works rally cars had aluminum bodies with fiberglass hardtops as opposed to the steel bodied production cars.  Has this presented any special challenges in the restoration efforts?

Actually the rally cars had a steel body with outer aluminum panels (bonnet, doors and rear wings). I learned that it is difficult to repair dented aluminum panels, so one door skin was replaced as well as the middle section of the bonnet. Fortunately there was no contact corrosion between the aluminum and the steel panels. It was quite easy to remove the fiberglass top because it is sealed and bolted to the body.

 

JW:)  This particular car won it's class in the 1964 Tour de France and came in 10th overall.  What other rallies did this car compete in and how did it fare?

 ADU 7B is the most successful car of all the works Spitfires. It competed in 5 events: 1964 in the Alpine Rally (3rd in class), Tour de France (1st in class, 10th over all), and Geneva Rally (1st in class) and in 1965 in Rally Monte Carlo (retired) and the Alpine Rally (retired). In 1966 and 1967 it competed in some French events.

 

JW:)  The rally cars were different than the LeMans cars in that they were specially equipped with extra lights as these cars were raced on public roads in all weather. What other equipment distinguished a works LeMans car from a works rally car?

 The main differences are the full aluminum body of the Le Mans cars and the different styling of the bonnet. The Le Mans cars used (in1965) special light weight chassis frames, the rally cars used strengthened standard frames. The differential ratio of the rally cars were shorter for better acceleration (0 to 60 knocked down from 17 seconds to 10 compared to a standard Spitfire) as the one for the Le Mans cars were longer for maximum top speed for the long straights (134mph to 95 on the standard Spitfire). The Le Mans cars had a special light weight shovel in the boot for the case that the driver had to dig the car out of  the sand banks which were piled up in some of the tight bends. There was also some different developments from 1964 to 1965. The rally cars used the aluminum head already in 1964 whereas the Le Mans cars used the cast iron head in 1964 and the aluminum in 1965. The rally cars used in 1965 a prototype 1296cc engine which were a forerunner of the engine introduced later in the 1300 front wheel drive Triumph saloon and the MK III Spitfire, the Le Mans cars used in all 3 events the 1147cc engine.

 

JW:)  It's been suggested by many that these rally cars were the forerunners of the GT6 that came along in 1967.  Based on what you have learned about your car, would you agree with that assessment?

 No, that’s not true. The PR-department used the phrase ‘born in Le Mans’ for the first sales literature of the GT6, but the GT6 was already developed and a prototype was already finished when the work on the competition cars begun. Actually the shape of the Le Mans roof was taken from this prototype.

 

JW:)  What are your plans for this car after you finish the restoration?

It will go definitely back to rallying. The good thing is that the car does not need to be modified for rallying like what would be mandatory with a Le Mans car (FIA roll cage and other safety equipment). As I am not an experienced rally driver I will start with smaller events and may be later I will go for some events the car competed in the old days, like the Alpine Rally or Geneva Rally.




Michael, thank you for sharing your experiences with us.  I know as an early Spitfire owner myself, this has been particularly interesting.  It is certainly nice to see that someone has taken an interest in Triumph's historic racing past and is trying to preserve a piece of it.  Congratulations, and good luck with the project.

For those who have a further interest in this car, Michael has an website dedicated to ADU 7B.
