ユーゴスラビア侵攻
The Royal Yugoslav Air Force acquired 24 Mk I aircraft from RAF stocks and subsequently undertook a licensed production run of some 36 aircraft. Tooling up for the production of the Mk IV was about to commence when interrupted by the Invasion of Yugoslavia in April 1941. Some 20 partly completed airframes, as well as production tools and spare parts were subsequently sold by Germany to Finland.
