The Bristol Jupiter was a British nine-cylinder single-row piston radial engine built by the Bristol Aeroplane Company. Originally designed late in World War I and known as the Cosmos Jupiter, a lengthy series of upgrades and developments turned it into one of the finest engines of its era.
The Aero A.30 was a biplane light bomber and reconnaissance aircraft built in Czechoslovakia in the late 1920s. It originated as an attempt by Aero to improve the performance of the Aero A.11, but soon evolved into quite a different aircraft, larger and more powerful than its predecessor. The aircraft is readily distinguished from other related types by the difference in spans between its wings – the upper set being of much greater span than the lower.
The Aero A.32 was a biplane built in Czechoslovakia in the late 1920s for army co-operation duties including reconnaissance and tactical bombing. While the design took the Aero A.11 as its starting point, the aircraft incorporated significant changes to make it suited for its new low-level role.
The Gnome-Rhône 14K Mistral Major was a 14-cylinder, two-row, air-cooled radial engine. It was Gnome-Rhône's major aircraft engine prior to World War II, and matured into a highly sought-after design that would see licensed production throughout Europe and Japan. Thousands of Mistral Major engines were produced, used on a wide variety of aircraft.
The Bristol Titan was a British five-cylinder air-cooled radial engine, designed and built by the Bristol Aeroplane Company in the late 1920s. It had the same size cylinders as the earlier Bristol Mercury engine, 5.75 in × 6.5 in, and produced between 200–240 hp (150–180 kW). Later versions of the Bristol Titan also used a Farman-style reduction gear produced by Gnome-Rhône.

The Bréguet 730 was a French flying boat of the 1930s. Built to meet the requirements of the French Navy, it was ordered into production but no aircraft were delivered before France surrendered to Germany in June 1940. Four remaining incomplete airframes were completed after the end of World War II, serving with the French Navy until 1954.
The Dornier Do R Superwal was a German flying boat airliner of the 1920s.
The Farman F.70 was a 1920s French passenger and mail transport aircraft designed and built by the Farman Aviation Works. It was a smaller counterpart to the company's popular F.60 Goliath. The F.70 was an unequal-span two-bay biplane with a wooden fuselage and was powered by a Renault 12Fe piston engine. The pilot was seated in an open cockpit behind the nose-mounted engine. Behind the open cockpit was a cabin for four passengers or freight.
The Bratu-220 was a Franco-Romanian prototype three-engined airliner of the 1930s, built in France.
The Gourdou-Leseurre GL.30 was a racing aircraft built in France in 1920 which formed the basis for a highly successful family of fighter aircraft based on the same design.
The Potez 32 and its military version the Potez 33 was a single-engine French monoplane transport built by Potez and based on the Potez 29 biplane.
The Lioré et Olivier LeO 20 was a French night-bomber aircraft built by Lioré et Olivier.
The Farman F.150 was a 1920s French twin-engined biplane designed by Farman as a day bomber.
