Do you know this car?
1 point for you.
(I hope my source is reliable on this!)
It looks French. Darmont related?
I have to say it does look French, but the V-twin doesn't really fit unless it's a Darmont. The image is a bit unclear, and I can't see if that's sliding-pillar suspension. It could well be.
Is it British then?
D'Yrsan?
Sandford ?

It raced in France but the builder is not from there.
His name is not related to Darmont as far as I know.

Sandford ?
I have the builder's name and it's not any of the known ones. I couldn't find out if the car was known under a different name.
If it's any help, the usual French marques were Ruby-powered and that is most definitely a V-twin! I'm guessing it's a JAP.
I just know it's an air cooled twin and front drive...but there was another model, an RWD with a water-cooled four.
Did it race at the Bol d'Or ?
I do not know...the year is 1931.
Was the builder from Belgium?
Not from there.

Go 150 km east of Bruxelles and you'll find the place.
From Aachen (Aix-la-Chapelle)?
Some more further east.
Cologne? Or somewhere in between?

From Aachen (Aix-la-Chapelle)?
10/15km east of Aachen

about 50 km West - South/West of Cologne
From Stolberg?
Yes! He was a civil engineer from Stolberg.
Any chance to find it online?
I took it from there..but as usual I had to do a little detective work to find the details.
Was his name "Schmied" ?
Nope.
The engine/chassis sketch looks very similar to the BSA 9 HP three wheeler

Your picture is the same of the puzzle car's :o
So the puzzle car is base on BSA three wheeler chassis?
Unfortunately I do not know. According to my source, there were 2 models, 2cylinder air cooled and 4-cylinder with a standard transmission. The 2 pictures should show the 2 versions. 1 point for you, because you obviously found one of them.
Michael G.W. Metternich had written it's a D'Yrsan tricycle from 1930 with four-stroke four-cylinder engine and tubular steel frame.
But it is only the following handwritten note to the images available and the actual source I have not yet found.
"d'Yrsan-Wagen um 1930 - Die Karosserie ist dem leichten Fahrzeug angepasst und die rennförmige Aufmachung verleiht dem Fahrzeug ein schnittiges Aussehen.
Drei Modelle wurden gebaut, bei denen nur der Motor und die Karosserie verschieden sind. Die der Motoren hatten 904 ccm (mit stehenden Ventilen), sowie 972 ccm und 1089 ccm (mit hängenden Ventilen). Die entsprechenden Höchst- Geschwindigkeiten betrugen 90 km/h, 120km/h und 130km/h. Der ganze Motorblock lässt sich mit wenigen Handgriffen aus dem Fahrgestell entfernen."
But the information is always very well researched and the sources are mostly in the archive.
Alone the tricycle archive from Michael G.W. Metternich contains tens thousands of documents with infinite information in many boxes. Unfortunately, everything is messed up and it will take years sort everything again. I hope I will find time for it sometime. Actually I want to connect the archive with my own and make it long-term public anyway.

More detailed images of the D'Yrsan chassis shown in your post:
Thanks for the pictures. :D
I found an article that was probably the source of M.G.W.M.? The photos are not labeled there with D'Yrsan but there are no other photos in the article and the D'Orsan tricycle is described there.

I haven't the time to translate all of that right now, so I'm not sure if that article mentions the name of the German Dreirad builder (solving this puzzle), but I think the puzzle vehicle is far more likely to have been built on the D'Yrsan chassis than on the BSA chassis shown in the initial post. My guess is that PJ's source included an unrelated chassis photo either by mistake or because accuracy was simply not a priority.
Interestin developments.
I'll post my source soon.
"H____ H___ Civil Engineer from Stolberg Rhineland". This is what I have.
A wild guess. Heinz Holt? (5 letters and 4 letters)
Not the right name.
Horst Herz?
Hexxx Hexx
Helge Heck ?
Henne Hess?
It is Henry Heck you are looking for. He is the author of the article posted by Hamburg-Automobilia. But according to the article he is from Antwerp in Belgium, not from Stolberg. And he is surely not the builder, but just presenting the D'Yrsan cylecar to the readers.

You are right. That was the name I was looking for...but it seems it was not the right one.
I think this is the best sum up of what happened:

It's a D'Yrsan. I found these 2 pics of a similar body:
I'm sure it's a normal D'Yrsan tricycle! I can not find a developer from Stolberg and otherwise I agree with the opinion of Wendax and Paul Jaray!
I think it's a D'Yrsan
I think we reached a fair conclusion. The car is indeed a D'Yrsan and my source (as suspected from the beginning) was not even close to accuracy. I gave a point each to Oguerrerob (who first guessed D'Yrsan) and Hamburg-Automobilia (who provided enough evidence). Thank you all for playing this puzzle, I don't think I'll use that source again!
