Here's my two cents worth. I own a 1970 model that is museum condition and it plays and sound great. It is a little different because it is 3/4 scale of it takes a bit of getting used to after playing my American Standard Jazz or my 30th anniversary Stingray. Still have the original case with all the paperwork after all these years. I don't play it so I've thought about selling it but am unsure what to charge for it because of the condition and rarity of it.
I saw in an interview that Jesse Keeler of Death from Above 1979 is always looking for these. Not sure how you'd get in touch but if it's really good condition, he might be interested.
