3./Jg 5 Claim 30/31 July 1942

My query relates to a claim by 3./JG 5 for a spitfire over Bergen area on 30 or 31 July 1942 at approx 16:30 hours.

I have a list of know pilots as being;
Ofw. Albert Faulhaber (also credited with shooting down a Hudson in August 1942)
Uffz. Schulz
Uffz. Forster
Lt. Steinicke
Uffz. E. Kahlert

This query relates to F/O J L Tully who was MIA in spitfire AA 800 (PR Mk IV) lost on a mission to Bergen 30 July 1942. To date this has never been a confirmed victory. I am trying to acertain the name of the Luftwaffe pilot involved and more details of the combat. Does anyone know of if any of the above pilots are still alive and if so how to contact them. 3./ JG 5 did not see much aerial combat during this time so it is likely this event would have been remembered.

Thank you
