Dettra flags no longer exists. It was bought out by Annin & Co. in 1994. The folks at Dettra had some sense of history, but the people running Annin could be making snow tires as far as their interest in flags is concerned. In the numerous moves the company has made since it was located in downtown NYC they have discarded so much treasure that historians and flag collectors would have paid big bucks for. But if it wasn't needed for current inventory, it was trash. Unless you can get copies of invoices from the power company that bought the Reddy Kilowatt flags you are out of luck. Sorry.
