You possibly saw my thread about identifying these little 4-wheel tipper wagons.

The kits were made by Trail Creek and the owner (Richard F) passed on the info that they are based on clay wagons from a brick works in Georgia. (Lots more photos in that thread.)
They are very nice little cars that I really enjoyed making, but they are taking up a lot of room on my shelves, and therefore I would like to find a good home for them.
As you can see, they look great in an industrial setting. They also work in a 7/8ths scale environment - this is an Emma with Richard’s cars.
I’d like to get back what I paid for them, so $175 for all 6 cars seems reasonable? (Message me if you want to talk about just buying one.)
