Magnat-Debon Type VMD
I have a Magnat-Debon BMA Type VMD with serial number 180.626. I would like to know where I can find parts and more info on this bike.

Magnat-Debon-1932c-VMD-BMA-1.jpg will be posted-1408

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.

Mon nom est David Ortega et je n'habite pas en Valladolid " Espagne " vous français cela a été avec un traducteur, et je vous écris pour cette raison: mon oncle a acquis Debon de 350 cc à un Magnat récemment et il veut le restaurer, donc il 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 trouvé cette adresse de courrier électronique pour le demander s'il peut me dire quelque tissu où il peut trouver quelque manuel du Magnat Debon, ou quelques images de l'assemblée du même les remerciements vous.

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 at

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?).
