For the first time in the history of British racing "photo finish" apparatus was used officially today at the opening of the Epsom spring meeting. The new device, which has been perfected after a long period of experimentation, differs completely with "photo finish" appliances previously tested. Equipment used by the RAF the low-level reconnaissance is incorporated in the equipment, and such is the speed of its operation that finished print of the finish is available to the judge in little over a minute after the horses have passed the post. Picture shows: photo finish of Great Metropolitan Handicap at Epsom today. Star song (D Smith up) is, to the camera operator, an obvious winner. So the "photo finish" camera is used to determine close horses. In the picture, only the hindquarters of Star Song can be seen. Into 2nd place comes Parhelion (E.Smith) with Salubrious. The 100-7 winner was ridden by D.Smith. 22 April 1947
