Have just re-read DaveF68’s post earlier in this thread and he stated that PM679 was at Farnborough before going to AFDU but that it didn’t fly with RAE until 2/7/43, or one day after your contact left!

I wonder if the station ORB (which should be at the National Archives) would give a definite date. You would think that an Fw 190 turning up might get a mention.
