Oddly named Księgowy (accountant) as this airframe was a gift of the Polish Association of Accountants to the LOPP paramilitary organisation. Jerzy Drzewiecki designed the RWD-10 as a single-seat aerobatic sport aircraft and fighter trainer. Some 24 examples were built between 1935 and 1938. During the German invasion of Poland, SP-BLZ was used as liaison aircraft in the Kraków area. Photo from: Narodowe Archiwum Cyfrowe
