Robert Frise - LMS Goods Van SNSO 837 awaiting restoration

One of a batch of 800 built in Wolverton this box van is of a later type. Originally fitted with vacuum brakes, this equipment was removed, probably on its sale to HM Dockyard, Portsmouth, where it received the number SNSO 837. (SNSO: Senior Naval Stores Officer). At the end of its life with the Navy, it was sold to the scrap merchants Thomas W Ward Ltd., who purchased it from the Royal Naval Armament Depot at Bedenham, near Gosport. It arrived at Quainton on 17 August 1978.
