BULGARIAN FIGHTER COLOURS 1919-1948 VOL.2 9137 Delai:3 semaines MSH356

Bulgaria's air force was very active in WWII, first against the armada of US bombers and their fighter escorts in 1943 and 1944, then, following an about-face in early September 1944, they battled their former ally, the Germans. This notable air activity is largely unknown outside Bulgaria, and is not very much popularized even within the country, despite fully deserving the utmost attention.
