Guys, thnx for reading my poor English.
F4UDOA,
WW2 era, many IJN/IJA pilots can understand/read English.
but, i think They called ''Gura-man (Grumman)'' for all ''blue carrier fighters''.
F4F,F4U,F6F...
maybe, F6F is ''newtype Gra-man'', F4u is ''Gra-man with gal wings''
and japanese civirians (peoples) know these name ''Gura-man''.
My grandmother's sister said,
''american's 'Gra-man' tryed shoot me when I was student''.
so, U.S.''Gra-man'' plane factory is most popular name in WW2 era japan.

###no probrem about her, the 'Gra-man' pilot was dweeb vulcher
###she is living now.

:D:D
btw, F6F nickname is ''Kuman-bachi''. means ''bear bee''(Bumble bee).
because these engines sound is very noisey like bee, I think.
B-24 nickname is ''Con-sori'' means these factory name.
sometimes B-24, B-25, B-26 are called all''con-sori''.
but, B17 is special.
its very dangaous bomber with many MGs. so, pilots know these name is ''model17 bomber''.
p-39 nickname is ''Iwashi'' means 'a kind of fish'
''Iwashi'' is very poor & small & cheep fish.
Zero pilots could shot down them easyly like ''eat breckfast''
I dont know p-47 nickname in japan WW2 era.
I will read more books about these intersting Info.
thnx
