'The Home Fleet's summer exercises. A Blackburn Ripon plane dropping a torpedo which can be seen [in uncropped photo] striking the water. This picture was taken from H.M. aircraft carrier Furious.' Some searching reveals that the year was 1933 and the unit the FAA's No 811 Sqn, with a red fuselage band. S1572 was built as a Ripon IIA but may have been modified to IIC standard with metal wings.
