As soon as I saw 'Silver Duster' some other names came to mind - - Gold Duster, Feather Duster, Dart Lite, etc. I recall having old brochures but likely lots of photos out there if you search. Try barnfinds.com. then do individual searches. Lots of good stuff.
I was able to do all the research needed . The description of the details on page two of this thread. Duster custom. With custom decoration package interior. A63.
