Hi gang. I picked this up and am very interested as to the year of this bike. The hub has the numbers 68 and after a space, 7. The serial number on the bottom bracket is 4285699. I don't know how to thumbnail pics, but I took a couple shots of it here: http://www.flickr.com/photos/2045379...7603122348506/

From what I've been reading, the two digit stamp on the hub indicates the year (so 68?) but I just wanted to be sure. Thanks so much for any info!
