GWR 41XX 2-6-2T No 4176 working a down slow approaching Dawlish Warren in c1956. Given the age of the coaching stock (especially the third vehicle which is a concertina all third), I thought this might be early 1930s but the Large Prairie did not arrive at Newton until October 1955 and it looks like a spring shot to me so it should not be before 1956.
