This is a hard to find item, it is a single ski set down sled. It is mad of wood and steel. Under the seat it has the two letters W and S, not sure if that was the maker or not. The ski is made of wood and has a layer of steel from the front to the back to make it go faster, and the supports for the seat are metal. It measures 14 1/2" tall, by 31" long, and the seat area is app 16 /12' by 5 1/2.
