I recently acquired a Lionel 6-28237 Reading U30-C, and knew the diesel in the box was not the Reading unit, has a C&O #3309 exterior. I have attached a couple pictures.
Question is how can I tell if it has just been repainted or the shell changed out? Or if there is even a way too.
Digging around I found MTH 20-20073-1 made a U30 in C&O #3309, but not sure how easy it would be to use a Lionel chassis with MTH shell. Also, the paint feels flat, not glossy.
Also, I could not find where Lionel made a C&O #3309 version.
Thank you
