Fairey FC1
Britain's other pressurised airliner killed by WWII.
Not quite a mini-Constellation, more a British-Excalibur, the pressurised Fairey FC1 existed as a full size mockup, but the project was terminated in October 1939. Fairey unsuccessfully attempted to restart work on the project in 1945.
Small scale models had a different window arrangement, with extra small overhead windows in the main cabin, and no eyebrow windows for the cockpit, and these features may relate to the attempted 1945 redux. I have chosen the window arrangement of the full scale mockup, as they are more likely the locked-in features of the aircraft if it had enterd the planned production.
