AMERICAN FLYER S Gauge 21910 -1/-2 Santa Fe A/B Unit

I have some old American Flyer trains that have been sitting in a dry basement for the last 40+ years and it's time to get rid of them. I don't know anything about grading them, but they are all in very nice shape.
These three are from the 1950's (purchased between 1959 and 1962) and are the 21910, 21910-1 Santa Fe B Unit, and 21910-2 Santa Fe A Unit. We have the original boxes for the A & B units. 24910 is missing 2 of the trumpets.
They have slight scratches, but nothing serious. All the lettering looks good, the wheels move smoothly.
If you have any questions, I will answer them to the best of my ability.
