I am just (belatedly!) reading "The Greatest Squadron of Them All" volume 1, which deals with the history of 603 Squadron up to the end of 1940.
In the intervening 17 years, I am wondering if anything more has come to light about the serials of the aircraft involved in 3 losses:

5 October K9807 (P/O Morton) - Chilham

7 October N3109 (F/O Matthews) - Godmersham, parts recovered post-war

7 October ????? (Sgt Strawson) - into the Thames Estuary

The book notes the confusion between the aircraft involved.
I can't seem to find the serial of Sgt Strawson's aircraft anywhere.
Is it known please?
Thanks,
Andy
