This is a set of two Walthers 932-5300 HO scale Bethgon coal hoppers. The hoppers are made of plastic and come in black color. These are unassembled kits with a two-rail system and an analog control system. They are replicas of the Bethgon coal hopper and were manufactured in 2009. The hoppers are in mint condition and are brand new. The set is suitable for children aged 12-16 years who are interested in model railroads and trains. The hoppers are undecorated and come with a corporate road name. The scale of the hoppers is 1:87 and they belong to the freight cars category. This is a great addition to any transportation-themed toy collection.
