It’s fine to use them; give credit to ‘601 Squadron Re-created’ and to the family of Norman Taylor who provided those images.
Sgt R.N.Taylor joined No 601 Squadron flying in Hurricane’s on the 7th of August 1940. Taylor scored his first victory on the 18th of August and two more during the Battle of Britain. He baled out of his Hurricane(P3735) on the 31st of August 1940 at 13:30hrs. He had been in combat with a Bf 109 over Gravesend. Taylor was awarded the D.F.M. on the 29th of July 1941and the D.F.C. on the 15th of December 1942 for shooting down a Foke-Wulf 200 Condor as a “Hurricat” pilot in 1942. In 1943 he became a test pilot.
