Tracker, thank you for the link... I visited this thread but no information about EN190 and her code.
The only thing I found it's the confirmation of EN190 and EN520 in 81 Sqn during the same time late April 1943 .
From 81 Sqn log book => EN520 Flown by C. F. Gray 29-4-1943 and EN190 flown by another pilot (P/O D. F. Husband ?) 30/4/1943...
