Last week at a swap-meet in Netherlands I found this 0 gauge American Flyer set of 3 cars. It is very rare to find that kind of thing here.
The coach and observation both have number 1206 and name Seattle. I wonder, did they have a separate catalogue number to distinguish them?
Here is a run with a American Flyer 401 as pulling power. I do not know whether that is a correct combination, but it looked good to me.
