The Finnish Air Force ordered two enhanced prototypes of I.V.L. D 26 Haukka I. The first prototype of VL D 27 Haukka II (HA-40) took air on March 1st, 1928. The comparison to the British Gloster Gamecock II proved both aircraft quite equivalent. However, the Finnish Air Force ordered a pattern aircraft and licence to build 15 Gamecocks on March 28th, 1928. The second prototype of the VL D 27 Haukka II took air on August 8th, 1928. Both aircraft were written off on July 1st, 1933. The aircraft (HA-41) is a prototype. (Ilmailumuseot.fi - Aviationmuseums.fi) [Nikon D300s + Tokina 12-24mm/4]
