yes, but the P-108 is the actual plane, te F4U-2 is just a mk of the corsair and contributes to the whole corsair number built 8) and remember, 12 of those 35 p-108's were transport versions 8)
There's where your friend got the information for the captured Corsair from. And there's plenty of captured aircraft on there, enjoy. I can't find anymore on any other German captured Corsairs.
