It is identified as a Berliet GLR 8 1960 by Heuliez on a dutch site containing plenty of images, but also remarkable identification errors. And it is identified as a Renault 2,5 T from 1952 also bodied by Heuliez on Flickr and Pinterest. Focusing on the logo, it could be a Berliet but the wheels are definitely Renault. This remains a mystery for me. Maybe a mix, at the time when Renault took over Berliet ?
