I saw that thing awhile back, makes me feel good about putin the 37 I've got on ebay!

 

$55,000 for a knuckle. Damn. I have seen some on ebay in a little better shape then this bike for $60K+. These old knucles are almost priceless any more and really belong in collections or in the HD musium. Even Pans are becoming very hard to find and most bring around $20,000.
