US Gypsum in On3 scale - the Western Hoppers 1-20

Another step forward in my US Gypsum project. I've measured USG cars several times before. And now it was time. I'm currently designing a digital mock-up of the first generation of Western Hoppers, numbers 1-20. I've made good progress, but as always, some measurements are missing. Perhaps some of the readers of this report have also measured these hoppers as well and can provide assistance. I would appreciate that, and I'll then fully implement my model, which is being developed in On3 scale, as a model. The goal is certainly to produce this model in brass. For the initial trials, I'll still conduct a 3D printing first. Looking forward to feedback.
