Some models from the 1920s had OHV Blackburne engines.
Magnat-Debon components were used in Nougier motorcycles.
(Top) On the Magnat Debon flat twin a single tension spring returns both valves to their seatings. Below is shown the tool drawer under the carrier.
Magnat Debon.
A flat twin engine embodying several novel features is carried in a cradle attached to an equally unusual frame. In the sump of the engine is a simple two-speed gear, and a cone clutch is mounted externally, the final drive being by belt. Opposed valves are employed, the exhaust being overhead, and a single tension spring working through rockers is utilised to return both inlet and exhaust valves. Mechanical lubrication is used.
In addition to spring forks both saddle-pillar and rear portion of the frame are sprung, and all springs are totally enclosed. An extremely neat metal tool drawer is fitted directly below the carrier and contains a very complete outfit of spares, as well as the necessary tools, each in its own special compartment.

1950 M3T "racer" (?)
Engine - M3T, Number - 298 829, 100cc, 1950
Frame number 334271
I am looking for any information that anybody may have on this Magnat-Debon motorcycle. I have been told its a "racer" model ?. What would be helpful is any photograph of what the motorcycle should "look" like as a restored finish or as it came from the factory in 1950 ? Also, is there a contact for any purchase of spares (where available) I could have ?
Any history or correction of the model of motorcycle would be greatly appreciated.

Editor's Notes:
There is a page on Terrot serial numbers here:
http://terrot.france.free.fr/index.php?page=datation
This this would make Frame # 101344 date from 1930, if Terrot and Magnat Debon use the same sequences. However, the information below only serves to confuse the issue.
Yesterdays have a record:
Magnat Debon 1929 Type BST 350 cc s.v.

NB:
Wikipedia mentions a Blackburne-engined 1930 model. They also have an image of a Terrot-engined Magnat Debon Model BSG 350 cc 1930 which is quite similar to the Scottish bike pictured here.

Models in this range were VMD, VMDO, VMDG, VMDOG, VMD2, VMDO2. There was also a range of Terrot machines which were probably very similar if not identical, apart from the marques. Admin.

This 2-cylinder motor cycle has about 500 ccm and was most probably built "around" 1910-1914. It was restaurated and operated by my father. It should be ready to be driven - it was driven last at the 2006 Horse Power Run in the Netherlands. Since then is is stored in a dry cellar. According to my father this is the only known Version of this 500 ccm model. There are 47 pictures at tangosierra.de/Magnat-DeBon/index.html. Get your own impression of this very seldom and historic vehicle.

m'a dit que s'il puisse trouver quelque manuel
d'assemblée de ce modèle dans court un Magnat
Debon 350 cc de l'année 1929, alors j'ai

Another one of Sheldon's lousy translations. Needed
the help of BableFish on this one:
My name is David Ortega and I do not live in Valladolid " Spain " French that was you with a translator, and I write to you for this reason: my uncle acquired a Debon Tycoon 350 DC recently and he wants to restore it. He asked me to find a handbook of assembly of this model, year 1929. I then found this address of electronic mail to ask if someone can tell me where he can find a handbook or images of the assembly of the bike. Thank you. -- Dosix

I am looking for information on a Magnat Debon, built in
the twenties. It has a two-stroke-engine with two
exhaust-pipes in one cylinder. I wonder if it has 98 or 175
ccm - that is all I could find in my books. It would be
great if anyone would have further information (technical
data, maybe a picture?).
