Good Morning, Oppo.
Today we have a Pan American World Airways Boeing 377 and an Opel Kapitän. The Boeing 377 was a commercial derivative of the C-97 freighter, which itself was derived from the B-29 Superfortress. Boeing squeezed a lot of airplanes out of that basic design. While the 377's double-bubble pressurized fuselage made for lots of room, nagging problems with the engines meant that only 55 were built.
As for the Opel, you’re on your own. All I can tell you is that it’s a 1953 or later.
