Arthur T Harris, (Marshal of the Royal Air Force Sir Arthur Travers Harris, AKA Bomber Harris!)

[Kohima]

Well spotted, Veg!
Bleedin’ obvious when it’s pointed out.
As said by Vince, some decent close ups would help..

Wow. What an item !

OK, here we go....one or two I can't make out, but there are : -

Bill Townsend - Pilot, AJ-O on the Raid.
Lance Howard - Navigator, AJ-O on the Raid.
Dave Shannon - Pilot, AJ-L on the Raid
Don MacLean - Navigator, AJ-T on the Raid.
Jim Clay - Bomb Aimer, AJ-W on the Raid.
Basil Feneron - Flight Engineer, AJ-F on the Raid
Fred Tees - Rear Gunner and sole survivor of AJ-C on the Raid ( very rare signature ).

Blow it up a bit, and the others should be easy to make out. It's worth a bit.....

And a couple more...

'Hobby' Hobday - Navigator, AJ-N on the Raid.
Len Sumpter - Bomb Aimer, AJ-L on the Raid.

Also, there's 'Johnnie' Johnson ; but there were two 'Johnnies' on the Raid ( in AJ-T and AJ-N ).
In the WW2 RAF, everyone with the surname 'Johnson' was automatically nicknamed 'Johnnie'....
