Here's an interesting Super O set from 1958. Lionel 2507W set with single motor 2242P New Haven F3 and matching 2242C b-unit and five cars.
Here's the set with the com ponent boxes:
Some close ups of the locos:
There should be a billboard sheet with the set, but I didn't get it. I bought this from the original owner. It was a woman. Her dad got it for her when she was 2, but she wasn't allowed to play with it much. She also had a 628 44-tonner set that she was allowed to play with. The 628 set was not this clean.
Here's the cars -- 3444 animated gondola, 6464-425 New Haven boxcar, 6424 flatcar with autos, 6468 New Haven double door boxcar, and 6357 caboose.
Everytime the car boxes are handled the flaps get a little worse. They're all there, but they fall off easily. This is really common with train boxes that have spent decades in Arizona. I think it's air conditioners pulling all the moisture out of the air leaving the boxes dry and fragile.
Here's the set box, component boxes, and small bits:
And it comes with a circle of Super O track.
This is a neat set that cost $65 new.
