What’s that page from, Jane’s? I’ve got the 1945-46 reprint, but it doesn’t have the nice cutaway drawing.
I have no idea. I just Googled "F4U Cutaway Drawing" and found one with decent detail.
The website where I "borrowed" the cutaway drawing was this:
https://history.scale-model-aircraft.com/wwii-aviation/chance-vought-f4u-corsair
And that page lists as one of it's sources the book "Fighters 1939-45: Attack and Training Aircraft." The book's Amazon page:
Hope this helps.
Duh @ me. The caption under the cutaway drawing at the source website says "image source: An Illustrated Anatomy Of the World's Fighters" and gives a link to the Amazon page for the booik:
