Q. What air force did this plane belong to?
Answer. Finnish Air Force. The swastika was in use from 1918 until the end of 1944.
The Stuka shown was a “red herring”. The Finnish Air Force had a variety of aircraft during WWII from different countries – Germany, Britain, Russia and Holland. German aircraft included the JU-88 A-4 and the ME109 but no Stukas. The blue swastika was considered a good luck symbol.
