Here is a two page article from the Jan-Feb 1963 issue of ARMOR magazine that takes a look at the French ELC light tank project.  This vehicle never entered serial production and it does not appear that much information has been published about this odd little vehicle in English (the wikipedia page for this vehicle references mostly foriegn language sources.)  This vehilce is roughly comparable in time frame, role and mission to the US M56 Scorpion and M50 Ontos.  Click on the images below to view the article page.
