Well, what do you know! (I'd mention this over on RyPN and see who responds!
Orchard Supply was famous at one time for railroad-themed calendars.
I got the model of the title (my blog post). It has a real box car. See the "Orchard Supply Hardware" section on Wikipedia. Oh! this is a prototype modeling. Does anyone know the circumstances behind the release of this MDC-Roundhouse AAR 40-foot boxcar? The coloring is very similar to the 25th anniversary model of the New Jersey Coast Model Railroad Club released in 1976. I imagine the club car imitated the "OSHX 1" model.
