Villeroy & Boch? The country of origin of that company is the same as that of the designer of this aeroplane.
Bathtub? This aeroplane has nothing to do with Etienne Dormoy or the Aeronca C-2!
Remake? Well, I'll explain the cheat. That depicted is a 60% scale model but which was built from scaled down versions of the designer's original plans.
There was one full size version of this specific model that did fly - in a country not far from you, SLB. There may have been as many as four of the general type, from which this specific model originated, of which at least one is extant (I was in contact with its owner only yesterday).
