stumbled on this thread and figured I'd throw in a few from my herd that might be appreciated here: 1953 Western Flyer X-53 (colors are technically "wrong," it's a long story) 1951(ish) J.C. Higgins, lots of mismatched parts 1959 and 1960 Schwinn Corvettes
Actually 3-D printed. The tank has portholes. I saw another model that had side pipes but they were 4 on each side. I designed them in a very simple program called Tinkercad.
