You're gonna have to take it apart (or have someone else do it) to determine if it really is all original. There is a BIG difference in value for an all-original vs a parts bass. That will also help you determine exactly which year it was built. It appears to be in very good but not perfect condition. Check ebay & the TB ads for an idea of the going prices.
I could be a wise guy and tell you it's only worth $200 and you should sell it to me, but I won't.
