Yes, I'm reaffirmingn here that the "original design" by Kenneth Howes, was non-hooded. His stated intent was a car that was like a raindrop. "From the very beginning this was a car whose theme included a relatively low front end, with headlamps in the corners, and with a waist line which rose relentlessly towards the rear where it ended with a pair of fins." (Robson)
It wasn't until later after the prototypes were built and wind tunnel testing was done, when the Rootes family got its hands on the car with the non-hooded headlights that the family thought the change should be made for the American market. They also sadly pushed the rake of the windshield more upright (and again on the S3), and added badges and things, whereas Howes wanted a car beautiful in it's own right, without clutter. "The car will obtain its beauty from purity in shape, relying less and less on bits and pieces of chrome trappings idly and often ostentatiously placed here and there on the body." (Howes)
There are pictures of the original buck and the running prototypes with the non-hooded headlights in McGovern's book and Robson's book. There is a really good picture of the original buck from the front - but it's not in any of those books (the rear quarter is in the McGovern book). I posted it once on this web site. But, that was in an early iteration of this website and it seems to have been lost. Maybe Ian or someone still has that picture. I think I got it from him originally.
FWIW, the original design did not have any bumperettes, just the horizontal bumper - all part of Howes "purity of shape".
