The interior was luxuriously furnished, with deeply upholstered seats, and an oversize cabin door was fitted to ease boarding and disembarking for the three passengers.
Alfred Victor Verville was an aviation pioneer and aircraft designer who contributed to civilian and military aviation. During his forty-seven years in the aviation industry, he was responsible for the design and development of nearly twenty commercial and military airplanes. Verville is known for designing flying boats, military racing airplanes, and a series of commercial cabin airplanes. His planes were awarded with the Pulitzer Speed Classic Trophy in 1920 and 1924.
The Stinson Junior was a high-winged American monoplane of the late 1920s, built for private owners, and was one of the first such designs to feature a fully enclosed cabin.
The Aero-Craft Aero-Coupe is an American, 2-passenger, semi-cabin, all-purpose, commercial biplane that was designed by Captain Clement Brown in 1928 and manufactured by Aero-Craft Manufacturing Company. The aircraft was intended for use as an air taxi, as well as for mail and express feeder service. The Aero-Coupe was manufactured by Aero-Craft Manufacturing Company, based in Detroit, Michigan. Aero-Craft Mfg. Co. was founded in 1928, and the Aero-Coupe was the first production model that was released by the company. The Aero-Coupe was a "semi-cabin" aircraft: the three passengers were situated within a closed cabin in the aircraft's fuselage near the nose, while the aircraft's single pilot was positioned in an open cockpit, above and behind the passenger cabin, behind the wings. The aircraft was first introduced to the public in 1928 during the Detroit Aero Show, also known as the All-American Aircraft Show, which occurred from April 14–21. Its price, as mentioned in Volume 20 of Flight International, was $6500, when it was first exhibited to the public. It was powered by a single, seven-cylinder Warner Scarab rotary engine, which provided 120 hp. The aircraft had a range of 740 kilometres, and was capable of flying as fast as 185 km/h. The wings were of unequal span.
The Eastman E-2 Sea Rover, also called the Beasley-Eastman E-2 Sea Rover, was a light seaplane built in the late 1920s for business and shuttle use.
The Swanson Coupe Model W-15 was a high-wing, cantilever-type monoplane produced in 1931 by Swedish aircraft designer and manufacturer Swen Swanson. Its design was considered innovative and the aircraft was viewed as part of a trend of producing safe and economical airplanes, which would appeal especially to automobile drivers. The Swanson Coupe was also designed to function as trainer aircraft.
The G.A.C. 102 Aristocrat or General 102 Aristocrat is a single-engined cabin monoplane built in the US just before the Great Depression. It proved popular, with over forty built; an early example was taken on an aerial survey of Antarctica. One survives.
The Simplex Red Arrow was a US single-engined monoplane produced in the late 1920s and early 1930s and intended as club machine or mail transport. Most used radial engines in the 90–110 hp (67–82 kW) range. They carried one or two passengers whose seats could be open or enclosed. One variant, the Red Arrow Dual Plane, was easily converted from monoplane to biplane and was available with two versions of the much more powerful Wright Whirlwind engines. In all about 20 were built.
