Bonjour Jean-Paul
Great to see your work with air gunner aces but regarding Henry Jacobs, RAF I believe most of the claims were not made as an air gunner.
You can read more about him on: http://www.jewishvirtuallibrary.org/jsource/ww2/sugar4.html
He must have been a radar operator during most of these claims. He flew with the night fighter Ace John Braham as radar operator during 1943 (claims 5 destroyed and 1 damaged).

Good luck with your work,
Peter
