Another interesting fact is the relative size of the aircraft is not that different.

P-51D:_________________________F4U-4:_______________Difference:
W=37'_________________________W=41'_______________ W=4'
L=32'3"________________________L=33'8"____________ __L=1'5"
H=13'8"________________________H=14'9"____________ _H=1'1"
Wing area=235 sq.ft.______________WA=314 sq.ft.________WA=79sq.ft.

Does anyone have comparative pricing on them?

I always like the P-38 but when I saw the cost it was rather eye opening. From a very fallable memory the P-38 ~$100K, P-47 ~$75K, and P-51 ~$50K. Of course how you come up with the price and when can create considerable variation but ...

Cost of WW2 weapons

Here is something from an old post by "Wolfy", I didn't look for your cost comparo exactly.
