You can use any of the old-time 36' reefer models as a core, etch new brass sides, and output decals on an Alps printer.
Yeah, well... Easy for you to say!

Actually, a Shapeways shell for an MDC/Athearn frame probably would be the way to go. Since this is a wood sided car with lots of scribing, I would think the rastering would be less of an issue.
Would still need decals made, though, but I actually do have side-on artwork. The Ute Indian with the Pikes Peak Route shield is full-color and the railroad name and car number are black with red drop-shadow.
....and the patent Railwire Threaddrift
TM is in full effect!
