We don't have the F6F-3. We have the F6F-5, modeled to perform like the -3.
We don't have the P-38H.
We don't have the Seafire MK.III
It is a subtype - I didn't include subtypes in the list. (at least according by not having separate arcile) - i.e. if the subtype isn't that significantly different - for F6F - there is a single article and no production numbers for subtypes.
Also I don't have data for Seafire III an
Now about P-38H, besides being subversion (also important one), also there were 601 P-38H produced - goes below the threshold I mentioned.
We don't have the P-36/Hawk 75.
You are right about that, according to wiki:
Number built 215 (P-36) plus 900 export Hawk 75 variants
So totally: 1115, but didn't noticed that there were two numbers that should be added.
...F4F-3 is the same case...
Don't we have enough US planes?
Take a look on the list: 5 out of 47 are US planes, and none of the missing major variants are fighters, 1 CV bomber and 4 bombers - which is quite low if you compare them to 13 UK, 9 Russian and 11 Japanese?
BTW I forgot to mention the Meteor that 3,947 were produced but I didn't written it into the list because it major production was post war - on the other hand many in there list were not produced during the war as were outdated.
