This much I do know... Haven't found one on Craigslist using craigshelper expanded to a 500 miles radius. Haven't seen a complete bike on eBay since I've been looking. Parts aren't easily found, there's a total of maybe 80 parts on eBay right now that will fit it, parts that were common to other bikes of the time.
I can't even guess at the rarity of the bike.
I'm going to go stare some more. I imagine it was beautiful when new.
