Photos of the back show really dark blue, especially on the neck. I wonder if the wear areas have reduced the aging of the clearcoat to expose the dark blue. It's not the first VERY DARK BLUE Azureglo that I have seen, but it is the second! A really dark Azureglo 4005 turned up at a Rickenbacker Confluence in SoCal in '05 as I recall, and a photo of it is in the book.
