Although wearing Finnish contemporary markings - which had nothing to do with the Nazis - it was actually a Swedish air force unit which fought the Russians from Kemi in northern Finland during the final two months of the 1939-40 Winter War. It had twelve Gladiator fighters and four Hart light bombers with open cockpits. Swedish Harts were all powered by Mercury radial engines. Note the skis carried for use by the crew in an emergency. This airframe did not actualy serve in Finland.

A beautiful aeroplane in the Laatzen museum, near Hanover. It was built by CKD in Prague during WWII . Fitted with skis in winter, Finnish Fw 44s remained in service many years thereafter.
