The product is a pair of ready-to-go Hornby R102 large mineral wagons in NCB corporate livery. These pre-built plastic models are in 1:76 scale and are designed to run on a two-rail system. The wagons are black in colour and are a replica of the National Coal Board's mineral wagons. Made in the United Kingdom by the Hornby brand, these OO gauge wagons are in excellent condition and would be a great addition to any model railway collection.
