Hi all, I would like to establish Wellingtons assigned to 311 Sq in summer-autumn 1940 for training purposes which had dual controls.
Unfortunately I am not able to find any reliable source - any advice please?

With use of a squadron diary and some Log Books I have put together so far following list of possible candidates which I would like to confirm & update:

N2880
R3234
T2561
T2577
T2469

Any help much appreciated

TIA

Pavel
