Just over 14,000 Windsor two door hardtops were built in 1957. Very few would have been ordered with non-standard paint options but there is no way of finding that number without going over the microfiche of '57 Windsor production looking at each car's paint codes and Chrysler Historical is not going to do those many hours of research. The dual (2 total) head lights were an early production factor for cars delivered to states which had not approved federal law permitting installation of quad lamps (4 total). I would recommend getting the $45 decode done by Historical as documentation of your car and perhaps it will turn up other interesting facts.
These are very pretty cars and yours would be striking in that color combination.
