No they are dutch. De Schelde was a Dutch aircraft and shipbuild company actually based in my hometown. The bomber was very probable designed in the late '30 ies. Don't think it has been build though, it was probably just a concept. Looking at the lines it seems to be developped from the Pander Postjager (Pander aircraft division was bought by De Schelde in 1934), so the design must have been made after that. I'll see if I can dig some info up for you.
Not much is known about these types, so good luck and I'll be very interested if you find anything.
Could be one of the types that De Schelde designed as a competitor to Fokker's G.2. In that case it isn't a bomber but a "Jachtkruiser", a multi-role aircraft.
