The following is from the Kenneth G. Wynn book, Men of the Battle of Britain:

“137301, Sgt Pilot, British, 501 Squadron.
Born October 22 1917, Henn was a civilian flying club instructor before the war. His flying experience enabled him to join the RAF in October 1939 as an airman u/t Pilot (906097).
After completing his training, he joined 501 Squadron at Kenley in August 1940. Henn claimed a He111 destroyed on August 30. He was shot down and wounded on September 2, after which he lost his operational flying category because of burns.

No images unfortunately. This is without doubt one of the most used books in my collection, not cheap, but worth every penny.

Hope this fills in the gaps.
Best wishes,
