Possibly the most offensive of these cars is the claimed "USRA" single-sheathed car. The prototype had three diagonal braces on each side of the door, where the Walthers model has two, mirroring the 1924 ARA design, not the USRA. C'mon, Walthers, get a grip. It's not remotely anything like the prototype you claim.
(Ben kind of said this too, but I think it deserves emphasis.)
