Czechoslovakian aviation company Avia built a long number of fighters designs during the interwar period. Almost all of them had decent performances, but it was with the 1929 BH-33E when they reached the first class level. Nothing new or innovative was done with the BH-33E, it was just the fruit of trial, error and perseverance.
Three examples of BH-33 were sold to Belgium in 1929 with the idea of built the type under licence, but without success. In 1936 one of those three was smuggled by the Republicans to take part in Spanish Civil War. The delivery was a true odyssey and when it arrived to Spain it was discovered someone had liberated the gun-synchronisation device…
The aircraft have been listed as a BH-33, but with that oval-section fuselage it could only be a BH-33E.
Boy, what a magnificently weird way to streamline those Jupiter’s pistons.
