I ordered logging cars and received them beginning of January, super quick too! For what it's worth I sent an email asking a question about an etched part that was in the kit and never received an answer.
I have no idea what the etched part is supposed to do, looks like a bunch of doors, but for a flat car? I think it likely ended up in the bag by accident.
The 25' spine cars mostly look good, unfortunately three of the twelve, the pewter did not fill the mold completely and they are missing a few ribs. Though for the amazing low cost of shipping and the rather low cost of these kits, I didn't complain, I can figure out how to use them anyway!
