Planet Models 122 Avia Av-135 Ljastovica

In August 1939, i.e. already under German occupation, the third Avia B-35 prototype, designated B-35.3, was tested. It had a retractable landing gear and a modified wing structure. It was presented at the aviation exhibition in Brussels with the German marks D-IBPP as an aircraft of the Protectorate of Bohemia and Moravia. The aircraft was designated Avia Av-135 (the Czechoslovakian designation "Avia B-135" is more commonly used in the literature). Bulgarian aviation interested in the fighter, which ordered a series of 12 Avii and 62 Hispano-Suiza 12 Ydra engines, and planned to build 50 license copies at the DAR plant. By 1942, all planes and 35 engines had been delivered. Bulgaria resigned from further deliveries and the purchase of licenses. The B-135 machines went to the aviation school in Lower Mitropolis. Most likely, one B-24 bomber was shot down during the 1944 raid on Sofia. The B-135 is a mixed structure, single-seat, single-engine low-wing aircraft.
