Greg: "This is one of 4 variations of Marylebone Class 115 blinds that I'm aware of. Brian Morrison's British Rail DMUs & Diesel Railcars shows two different variations on Page 128 (Top & Middle) and Page 128 (Bottom).
Assuming that the original blinds fitted to the Class 115 units had closed GC locations (e.g. Brackley, Woodford Halse, etc.) on them, this would date the blind from the 1970's."
