Hi Alex
The 125 Airfield ORB (Form 540 only) does not list any serials at all between June 1943 - July 1945, they would be, possibly, listed in the Form 541 of the relevant squadrons.
However, as we are all aware, you either get serials or individual letters, but very rarely both in a Form 541 - sometimes you just get lucky if you can find a pilot's logbook with both, but they are also as rare as hens teeth!!
However, see also:

By virtue of the report above stating
"F/Lt P H Bell killed in one aircraft", but not stating which, what does the 19 Squadron ORB have to say about this incident, as that should confirm the entry in the AB publication?
cheers
