I know of a 5E NID double trap gun that I think won the Grand America in the 1930s. I have to do a little more to verify the details but Im pretty sure the story is legitimate. The gun is in nice condition ST AE BT VR like a good trap gun. I have seen 4E double trap guns for around 3k but dont know of any 5E doubles that have sold.

What is a 5E double trap going for, if it was used in and won the Grand does that add premium, and what would the award for winning the Grand (a silver plate I think) be worth?
Thanks, Ross
