That one with blocky wingtip pods looks based on a Dornier V-TOL something which was in a picture the first real book about airplanes my parents gave me,
forget if it was Christmas or my birthday around 1974 -75. Was a large color photo book titled Aircraft by David Mondey, publisher Octopus. Is currently buried behind some other books in a stack across the room.
Am remembering all that but not the Dornier's type number & I'm not going to cheat on the internet.
