Carlton is a British bicycle manufacturer that Raleigh bought in the 1960's. I'll grant that the lugwork on that Supercourse looks pretty involved, the bike was absolutely made on an assembly line.
There should be a serial number somewhere on the frame. If you can find it and post it, we can tell you when, and probably where exactly it was made.
The Motobecane? I have no idea.
