Looks like I have a buyer for the deck, any interest in the ski itself? Any 10 inch deck could be mounted on it and you can Plunge down some hills to your hearts content.
Here's a link to some pics of it.

I rode it in the midwest about 10 or 12 times. Very little wear on it. It has mostly stayed in my closet for the last 31 years.
If you don't know about them...Tom Sims was one of the first snowboard builders. Back then it was called a skiboard.
