View of the Gloster III N194, the Gloucestershire Aircraft company's most successful racing seaplane. Two were built to compete in the 1925 schneider contest. Powered by a 700 h.p. 12-cylinder Napier Lion VII, the 20ft span biplane was completed in 1925. Trials were successfully carried out at Felixstowe in August in time for the two aircraft to be shipped out to Baltimore in early October.

Gloster III N194 pictured at Felixstowe following modification to the tail unit, after which it was given the designation IIIA. Although it was designed to feature wing surface radiators, insufficient time necessitated the fitting of the large ugly Lamblin units on the leading edges of the lower wings, as seen here. N194 made its first flight on August 29, 1925; Hubert Broad was the pilot.

Originally known as the Mars I and registered G-EAXZ, the Gloster I was later purchased by the Air Ministry and put on floats. It was used by the RAF High Speed Flight in training pilots to gain experience for competing in the 1925-1927 Schneider contests.

The Gloster I J7234 at Felixstowe in 1924. The dark areas on the wings are surface radiators. Fitted above the top wing is a coolant header tank, and J7234 is also fitted with the revised tail unit.

Following its success at the 1925 Schneider contest, N194 was given a curved leading edge to its fin.

J7504 was the first of two Gloster IIs built to a 1924 Air Ministry order at a total cost of around £6,000. Designed for the 1924 Schneider contest, J7504 sank during trials before the race. Test pilot Hubert Broad managed to escape.

N195, the second Gloster III, was first flown on June 3, 1925 by Bert Hinkler. It was flown only once before being shipped to the USA for the 1925 contest, held at Baltimore.
