Ok, ok, my knowledge of US WW2-era fighters is rather less than my knowledge of others. My knowledge base is roughly British>German>US=Japanese>Russian>All the rest.
The front end with the radial engine always puts me in mind of the Hellcat (and a lot of those US naval planes - Corsair, most of them...) I'll have to study up my US WW2 warplanes. You're right, though, it does have a Fw-190 look to it, though without the underslung intake of the Fw-190, the general impression is still more Hellcat/Corsair. To me, at least.
