Robert Frise - Toad Brake van in Down Yard siding

Very similar to No. 68766, this 27ft 0in brake van was based at Taunton in its final days on British Rail. The van was sold to the Oxford Ironstone Company, becoming their No. 3. They used it at Banbury until 1970 when it was purchased by a QRS member, arriving at Quainton on 23rd September 1970. This is an early example of a standard GWR brake van, code named Toad.
