JHZ563:
An FYI on the hopper, etc.: these are Lionscale cars (former Weaver tooling to my understanding) and new-design trucks painted in a Tinplate manner, and they are shiny like Williams pieces from the 90's - very. They sure look like my Weaver stuff. So a Weaver hopper of the same type will give you a good idea of the structure.
The number boards, etc, are separately-applied pieces, a la Pre-War.
One thing: this hopper has add-on metal grab irons; not sure about the final-production Weaver version.
"I have no interest in this locomotive"
Best part of the set - truly striking.
