(NOT) The first differential (UPDATE)

UPDATE by Baron Lafitte de Montripier: " I have to stress that it is by no means the first drawing ever made of a differential. The principle of that mecanism was known for a long time and its description can be found in technical manuals much prior to 1894. It was invented and patented in France by the famous mecanic Onesiphore Pecqueur, who died in 1852. I dont know the exact date of the patent but the "Musée des Arts et Métiers" in Paris would certainly be in a position to provide details and evidence. "

The drawing is attributed to Frank Duryea himself and it's most likely the first drawing ever made of a differential. Now this is only one little piece of the history that's written all over this American automotive monument. Chances are that it will leave the US to a foreign buyer. Just because all those American museums just didn't know about the existence of this car that certainly is the most important carfind of this century. As we don't have the time to tell all those museums, we suggest that you do so. And let them write to us their motivation to obtain this gem. At least if you share the opinion of experts like Rick Carey. See his emotional statement in Read More (photo Giorgio Bracaglia)
