Ted-

My travels to see bike parts from the era doesn't get me to within 1% of what you've seen, because YOU WERE "THERE!"

I've created a page on my Website that shows what I'm talking about with this 151 chainring:

Speaking of the CRVBA, while everyone is there, browse around and take a look at who won the 2005 CRVBA (Classic Rendezvous Vintage Bicycle Award)! Since the CR in NC will be in June, 2006, nominations and voting for the 2006 CRVBA winner will start just B4 X-Mas and end near the end of Jan. Lou Deeter will be announcing more details later.
