SOME FRENCH MACHINES AT THE SHOW
Aeroplanes Henry Potez
This firm is a newcomer into the aviation industry, as far as pre-War aviation is concerned. It is one of the firms which had not turned their attention to aeroplane construction until the War demand arose. It will, therefore, be of some interest to watch the future of the firm. At the Paris Show they are exhibiting two machines, one a passenger 'bus to carry four, and the other a little spotting two-seater.
The former - type S.E.A. VII it is called - is an enclosed biplane with seating accommodation for two or three passengers in addition to the pilot. The engine is a Lorraine-Dietrich, with which the machine attains a speed of in the neighbourhood of 200 kilometres (124 miles) per hour. The weight of the machine, all on, is 3,630 lbs. The overall length is 30 ft. 5 ins., and the span 46 ft. 2 ins.

Potez S.E.A. VII
The civil Potez S.E.A. VII was one of the first products of Société des Aéroplanes Henry Potez which had previously been known as Société des Etablissements Angevins and Société d’Etudes Aéronautiques, from which came the initials S.E.A.
The civil S.E.A. VII was a development of the military reconnaissance S.E.A. VII of 1918, and the prototype was exhibited at the 1919-20 Paris Aeronautical Salon as the Potez S.E.A. VII Limousine. It made its first flight in December 1919.
The Potez S.E.A. VII was a two-bay tractor biplane powered by a 370 hp Lorraine-Dietrich 12Da water-cooled vee engine. The wings were of equal span and had slight backward stagger. The two-seat passenger cabin was a square cab-like structure positioned aft of the pilot’s open cockpit and reached by a fixed ladder on the port side of the fuselage.
Production aircraft appeared in 1920, and the prototype made a special flight to Croydon on 16 July that year. Twenty-five have been reported, with all going to Cie Franco-Roumaine de Navigation Aérienne. They were used on the trans-Europe route and are known to have operated as far as Warsaw and Constantinople. It is believed that the registrations of the Potez VIIs ran from F-FRAA to F-FRAY. Known aircraft were F-FRAA (c/n 106) the prototype, F-FRAE, F-FRAF, F-FRAG, F-FRAP (c/n 121), F-FRAR, F-FRAY (c/n 133) and F-FRAW (c/n 134). Of these F-FRAP and F-FRAW passed to CIDNA in 1925.
Span 14 m (45 ft 11 in); length 9-2 m (30 ft 2 in); wing area 44-5 sq m (478-9 sq ft). Empty weight 1,100 kg (2,425 lb); loaded weight 1,650 kg (3,637 Ib). Maximum speed 200 km/h (124-2 mph); cruising speed 180 km/h (111-8 mph); endurance up to 2 3/4 hr.
