In December 2010, the magazine Automobilia published an article about the Rochet-Schneider 20CV and 26CV.
This article is very well documented. It appears that there are only two or three 26CV left, including the 29539.
Moreover, I have not found to date any document on other 26-Sixes built at that time except one “Faux Cabriolet”, the one seen on the advertisements and the one that was presented to the “Service des Mines”. It is not even sure that it is not the same one.
And don’t forget to have a look at the “soft auctions” in progress
