You are looking at a really cool HO Scale Santa Fe passenger car, a 4-4-2 Sleeper, car "Regal Pass:. Has scale couplers and detailed interior. I am not sure of the manufacturer. The last time I saw this car produced was by Walthers some years ago.
This one is tough to find in any condition. It is not often for sale on Ebay.
PLEASE LOOK AT THE PICTURES AS THEY ARE PART OF THE DESCRIPTION.
CONDITION: C-6. Some rubs, scratches. Roof is not snapped all the way in place--can't tell if it is just not snapped or if it is bowed. One coupler whisker is snapped off.
