Trop,
I just did exactly what you are thinking. My original was a little rusty but cleaned up nicely. I opted to have it duplicated because everything else has been total refurished. I will keep my original in a safe place along with my broadcast sheets just to be sure I know where they are. DataTags.com did a wonderful job on mine. All I had to send them was a photo of my original. Total price $50 plus shipping.
