Built to an Air Ministry specification for a ship board trainer and designed by F.A.Bumpas, the Sprat was in competition with the Vickers Vendace and the Parnall Perch. Not only was the plane to have a fixed undercarriage it had to be readily convertible to floats. Flying for the first time on the 26th April 1926 at Brough it went to Martesham Heath for comparative trials which were won by the Vendace. Owing to the financial austerity of the time none of the craft were ordered.
