Thanks for the pointers Franck
I have had a separate discussion with Andy Thomas regarding these Buffalos, and by discussing various photos and their merits we have a possible scenario like this.
805 Squadron were putting three Buffalos and six Fulmars ashore. If these Buffalos were followed by more, is so far not known.
The three were AS419, AS429 and AX814, probably coded as follows:
AS419 7X
AS420 7Z (port side coded 7Z, starboard side only Z)
AX814 7Y
This is nothing which is written in stone, but where I stand today....
Cheers
