The Seely was based on the earlier Tourer and was entered into a competition organised by the Air Ministry for a safe short take off and low landing speed passenger craft. The passenger sat enclosed behind the pilot's open cockpit. The competition was held at Martlesham Heath with only two other competitors, the Sopwith Antelope and the Westland Limousine. The Limousine won. Bristol kept the Seely for general duties, later selling it to the Air Ministry where it was converted to use a supercharged 435 h.p Bristol Jupiter III driving a two blade Leitner Watts propeller (see my earlier post) which raised the service ceiling to 24,000 ft.
