Great posting Ron. I’ll add a few. I think the Older Atlas gons are great in every way except weight, but that’s easily fixed. The newer Atlas Trainman gons are even better—same tooling, more weight.
I’m a prototype waybill operator, and part of a 14-member group, so I need to have a freight car fleet that reflects the New Haven RR and other lines of the late 60’s early 70’s PC. There are, of course, exceptions to that rule.
40’ AHM 70’s gon repainted NH. The little red symbol to the left of the reporting marks indicates an injury in the project. In this case an x-acto knife rolling off and doing a vertical puncture in my foot….just after finishing my decal work….
50’ Weaver war-emergency gon with light weathering. No story
Atlas 53’ gon, 70’s production. I’ve been fascinated with the Roeblings (of Brooklyn Bridge fame). When I found an old set of Champ decals it was “game on.”
another older Atlas 53’ gon repainted for interchange with another operator. 
70’s kit, a bit of a challenge to assemble.
an old KUSAN gon, stretched in length and width to needed dimensions.
Atlas 70’s gon (Reading) rebuilt into a P&W 70’s “super gon.” The sides and ends were made separately and sold by K -Line. Prototype photos of this car, like many of my fleet, are on rrpicturearchives.net
last but best is a Lionel gon from a few years ago. These are great as well, with exceptional detail.
You might notice I haven’t included MTH gons. I find they generally sit too high, reducing the prototypical appearance. Nothing wrong with them, and I do have a couple, they just don’t “spin my wheels” as a manner of speaking.
