Unknown maker, I'd say around 1940. I replaced the original 80-year-old trucks, which already had hi-rail wheels (Lionel PW, actually), with some NIB "Peare" (about the same age, I'd say) trucks which have hi-rail dummy couplers which I had found on eBay years ago. They are cast "soft metal" (fancy lead), and roll about like PW Lionel trucks. I painted them with camo brown. I replaced the original trucks because they had no couplers and the couplers mounted on the frame were scale O.
The decals - except the reporting marks - are original. I left them, even including the mistakes. I used a brush and craft store acrylics to cover the peeled bare metal areas, using a flat burnt umber and a flat black. Light overspray of R-O-L camo brown, then Dullcote.
The car is all die-cast zinc and properly heavy, but not crazy-heavy. It's a tank built like a tank. 1:48. No missing steps or the like. I did replace the missing/damaged ladders to the dome from some brass ladder stock that I have. A good scale model. These oldies are often the best things around, and I get a kick out of refreshing them for 3RO.
I like the way that the big O-gauge couplers tuck under the frame unobtrusively; the short shanks help with this. Too bad that modern 3RO cars couplers' keep getting more and more extended and noticeable.

The C&O hopper and B&O brass boxcar in the background are upgraded oldies, too. I painted the boxcar.
