The three planes belong to 5./JG 54 (black 5, 7 and six). The photo was shot in summer 1943. Maybe during at the battle of Kursk or shortly before. The camouflage was typical for JG 54.  The group symbols on the hood and under the cockpit (greenheart) are overpainted with green color.

Luftwaffe ace Franz von Werra escaped from a prison train bound for the camp at Neys, Ontario, and successfully crossed the half-frozen St. Lawrence River to reach the still-neutral United States.  Although von Werra glamorized his story for reporters, there is no doubt that his was one of the most daring escapes undertaken by a POW in Canada!
