This board is was made in Waterford NY by Al's American Dart Boards. They are no longer made and hard to find.
This board is also refered to as a Troy Board.
It is from small blocks of basswood clued together. There are wire dividers between each segment. The trademark was the extra bullseye placed just outside the number 6.

That looks pristine Mark, has it never been used?

Never used. I actually have two of them. The one I have was new in the box with two sets of feathered darts. The boards are also signed by the maker on their stamp on the side of the board.
