I over paid ($4) for an AHM 40', DS, DD box car thinking I needed it for a upcoming project. That project didn't materialize as I envisioned. What to do with the model? I took it out of the box and gave it a good look-see. The roof looked like something I'd seen before, so I cut it off. Is this roof usable? If so, what box cars had it?

All comments are appreciated...Well, all favorable comments anyway...
