Gresley 4-6-4.

Class W1 No. 10000 at Doncaster c. 1938. It had been rebuilt in 1937 from the experimental four cylinder compound "Hush-Hush" which was built in 1929 but never particularly successful, but unlike all the other streamliners was never named and was withdrawn in 1959 as BR No. 60700. A colourised b/w photo, but photographer unknown.
