Steve, you got it exactly right! The 2nd Atlantique, the one that was recently restored and won Pebble Beach, is owned and shown locally and is flatout gorgeous. The Bugatti door opening scheme, as per the pic, might work on the custom 444, too, though suicide doors always make me slightly nervous. More likely is a conventional door arrangement, using original parts of the forwardmost door frame/hinge.
I'm glad you like it!
