4900 1929c Old Oak Common
GWR Hall class 4-6-0 No 4900 Saint Martin at almost certainly Old Oak Common shed in c1929.
Frederick Elkins says "May I be so bold as to hazard a guess and say that this is Old Oak Common shed. 4900 is facing Paddington (if my location is correct) and has just come off the Bristol Passenger turntable. What used to be termed as the 4700 road is to be seen at the rear of the tender, with Old Oak Common carriage sidings and shed in the back ground".
