As regards the floorpans of the Boulogne racers, I would hazard a guess that they started with a production tourer steel floor and bulkhead. These were the first racing bodies built by the Works on the seven chassis, so it would make sense to start with the production floor and bulkhead. It would be easy to modify the floorpan by narrowing the two main floor sections. I believe there is a photo of one of the cars when it rolled during the race which might provide some useful evidence of the floor construction.
