    F6F Hellcat initial projects?

    Just realized that i have never seen any drawings of interim projects that eventually led to the G-50/F6F. There was an G-33 based on the XF4F-2 but with R-2600 engine, and as i understand initial G-50 projects had still much in common with the F4F (mid-wing, fuselage landing gear etc.). Are...

    K+W C-37

    The C-35 and the C-36 are well known, actually built, aircraft of "Eidgenössische Konstruktionswerkstätte" in Thun. The planned C-37 is rather less known. Last year I had the chance to re-work an 1978-article of "Cockpit" and I was lucky to get to see a painting of Roland Eichenberger -...

    Supermarine 312 cannon fighter?

    I've seen a few references to a Supermarine early World War II project called the Type 312. From what I've read, it was a derivative of the Spitfire but with standard cannon armament and a ventral radiator instead of the Spitfire's underwing radiators. Does any photos or plans or other details...
