The Walthers Proto 1000 USRA 50-ton Drop-bottom Gondola HO Scale Car 920-237061 Rock Island is a ready-to-go pre-built model train car designed for model railroading enthusiasts. With a multicolor design and a gauge of HO, this self-discharging car accurately represents a 50-ton drop-bottom gondola. Produced by the well-known brand Walthers, this car is a detailed addition to any model railroad layout, adding realism and authenticity to the collection. Perfect for hobbyists looking to expand their freight car collection with a high-quality, professionally crafted piece. I have a couple of these, so the pictures represent both of them. RI numbers are different. Has original box. 101E 0226.
