bomber boxcar

Does anyone have information on a company making HO bomber boxcars? I came across it on the web and lost it.These were rebuilt boxcars to carry bomber parts during WW II.I think it was a Canadian company,thanks for any help I may get,Riley.

Riley,
Have you tried a Google search ? In the Index of Magazines, there was one possibly applicable citation:

Aircraft Parts Car Mainline Modeler, August 1992, page 48 ( AIRCRAFT, FLATCAR, “HALL, EDWIN”, NMRA-4.19, PARTS, CONSTRUCTION, FREIGHTCAR, MM )

I have no idea if the cited article is for the right era. And, these two citations don’t appear to be the answer either.

The legacy of the Iron Horse - helps build the Iron Bird NMRA Bulletin, August 1970, page 40 747 parts shipped by rail ( AIRPLANE, LOAD, FREIGHTCAR, BL )

Railroad to the rescue - an airliner on flat cars Railroad Modeler, June 1976, page 56 ( AIRLINER, AIRPLANE, FLATCAR, LOAD, “MCGEE, PATRICK”, FREIGHTCAR, RRM )

Perhaps one of the Canadian modelers can help. Another thought would be to try the military railroading Web sites, for example:
