Type Werk.Nr Registration History
The Aero A.300 was a Czechoslovakian bomber aircraft that first flew in 1938 as a much refined development of the A.304 (despite what the numbering would suggest). Despite showing much promise, development and production of the aircraft was interrupted by the outbreak of World War II.
