I joined this group (mostly) to follow this build. It is a a really impressive build.
I don't know if this is of interest, or allowed, but I've been going through a stack of electronic documents I have. Mostly technical manuals for aircraft. And I seem to have a number of manuals / documents for RAF Phantoms (and other british aircraft of the era). Don't know if they're any use to you for your build or not, but here's a Dropbox link for them. They're are some large documents in there. And a lot of potential detail. Hopefully you'll find something interesting / useful.
