Let's see. The neck and tuners are worth $500 on eBay if the neck isn't warped. Pickup $180-200, bridge $50, body should be at least $250, neck plate with '73 serial number $150.
BUT: The body has the thumb rest holes on the E side, so it's '74 or later, not '73 as the seller claims. If the neck plate is '73, this could be a parts bass.
