This is a detailed HO scale (1:87) model building kit from the famous Walthers Cornerstone series. It's a machine shop with an attached boiler house and stack, perfect for adding industrial detail to your model railroad layout. The finished model measures about 8 1/8\ x 5 3/16\ x 6 1/2\ (20.6 x 13.2 x 16.5 cm). The kit includes parts molded in appropriate base colors, and the large doors can be assembled open or closed. It's designed to look great in 1930s and later scenes and can be built as a freestanding structure or attached to other buildings (like the Walthers roundhouse, sold separately). Important: This is a scale model kit with small parts, not a toy. It's intended for modelers aged 14 and up.
