Jan Zumback, the famous Battle of Britain Fighter Ace flew EN951 303 Sqn from late September 1941. Earlier in the year Jan was posted back to 303 as Flight Commander, and only 2 months later he was promoted to Squadron Leader and appointed to command the Squadron, a duty he performed from May until December 1942.
It was during this period Zumback had 3 personal Spitfires, all of them Mk Vbs coded RF-D, and all adorned with a Donald Duck symbol in front of the cockpit on the left hand side. For the third 'Donald', the artwork was unsurprisingly larger and more detailed than the previous 2 machines. Similarly, his personal tally was marked by crosses on the left hand side, confirmed kills being outlined in white, probable in red and damaged without outline.
