OK Clint
No idea who this 'Cea' is or what his info is, but since appx 50 F.5 were used by the Japanese,
most of them post 26.7.21 I am surprised that there are so many photos of 'Y' coded F.5 and
so few 'Yo' ones.
Should be the other way round....
Is there a list somewhere for Navy aircraft markings up to 1940 or so?
I think I am pretty well covered for the WW 2 period (think mind you....)
Cheers
