This 4mm. scale GWR Castle Class 4-6-0 tender locomotive fleet number 4073 “Caerphilly Castle” in Post 1927 livery was released by Airfix GMR during the period 1979-1981 (cat. ref. 54124-2). This model has been serviced prior to sale and is in good running order and little-used condition. The model is tender driven with power collection from the driving wheels. The traction tyres to the tender wheels are intact. The cab has two crew figures and whilst the brake blocks are fitted, the brake rodding remains in the un-opened sachet along with the screw coupling. The nameplates and cabside number plates are etched brass. The original box is in good condition with intact vision panel, a small tear to one flap at one end, and a good foam tray.
