This is one of the first 1980′s Burton Prototype Performer Snowboards that was converted into a longboard skateboard in its later years. Own a piece of history with this incredible board. This board was one of the first designs and was a prototype test used by Burtons staff which amazingly lacks some of the telltale signs of prior use. The pictures speak for themselves. As you can see the board was converted into a longboard skateboard in the early 90′s. Offers and questions always welcomed. First Prototype Burton Board measurements are.
