GWR 4-4-0 'Dukedog' class 3215 - BR 9015 c1955

This is from an assorted batch of postcards and loose prints from my father's collection. There is no indication of the location or date. I don't have a date for 9015's withdrawal - all, except 9017, were gone by 1960. I have guessed that this was taken sometime in the 1950s - it is clearly in BR days.
