Hi , Thanks for the comments everyone. the bike came from an estate sale in chicago.It has the # 2 28 68 on the bottom bracket. The lock nuts say cam 67 . the front quik release lever is flat. the rear has been replaced. The free wheel also has been replaced its a dura ace 22,20,18,16,14. the front chainrings are stonglight 52/48/40. it had drops on it but the wife needs the upright bars . the twin stiks were on it. I do plan on taking it to the wastyn shop to see if they could shed some light on it. I dont know if they farmed out any of their bikes or not. It rides very nice. thanks for the insite. Happy holidays to everyone. Brian
