The 'Iron Mink' is one of the most recognisable GWR wagon types from the end of the 19th century, with over 4,700 examples constructed between 1886 and 1901. Both underframe and body were built from iron and steel, creating a robust and long-lived wagon, with examples surviving into the 1960s. The metal construction made the design ideal for use as Gunpowder vans, wagons to the same style being used by other railway companies and private owners.
This model is finished GWR goods grey livery with 25in height lettering, as applied 1904-1920.
