Holy smokes! That is a rare, collectible bike and is the original un-molested condition that collectors want. Be careful with it and don't change anything or remove any parts. I'm just guessing here but if you put it up on ebay it could bring in excess of $5000. A lot of the potential buyers will be in Japan so you will want to think about shipping there. Also, if you have 0 ebay feedback that might be a concern but I think in this case the bike will speak for itself.
