HO scale version of the 1830s flour car as preserved in the B&O museum. Will fit a 28-30" metal wheel with a short (.950") axle if you don't want to use those provided. 33" will fit too with a little modification. Pretty much the same as a typical wooden shop car used throughout the 19th Century. The original was coupled with a link and pin, the link sitting on top of the drawbar instead of inside a slot. Part HOR14.
