What kind of car?

[Tom]

The "roof" of the car looks more like doors, maybe with a hinge at the top of each vertical, in the sides? Possibly multiple doors? The flatness of the "roof" also could be taken as an indicator of "doors", but why cover pulpwood?
What makes this worse, is that the car number, 508590, would have been assigned to a 33' 2 bay 5 ribbed-braced hopper! Formerly CB&Q.
The possibilities?
1. a "specialty car".
2. a figment of a toy train manufacturer's imagination.
3. a seriously misinterpreted mistake.

I'll take #2 for $100 Alex.

That is what it is. AHM, & Bachmann made them, and I think IHC later on from the AHM molds.
