Thank you all who replied to my ID question. My first impression was that it was a 1973 model that had been rebuilt with whatever Campy the then owner could get. This was solely based on my memory of working in the local Raleigh LBS back in 1976 and the few left over's that we had from previous years.
The bike purchase has a small story. A few months ago I decided to try to buy the bike I had back in 1976. I found the bike I got on Craig's list, contacted the seller and did not get a reply. So I went on to other EBay and Craig's listings, put in a bid on one bike but did not get it. Then the first seller got back to me and said that no one local (Portland OR) bit on his ad and he was going to have to ship it any way when it went on EBay. So he decided to save the posting costs and give me a first chance at it. Of course I said yes. The bike arrived and I dug into the box to see my 1976 Pro again. Well it wasn't the bike I was expecting. As I unwrapped the bubble wrap I recognized the Victor Brampton seat cluster. The 1976 turned out to be a 1974!
Which is great by me. Back in the day I wanted the older version but Raleigh did not have any more, the shop (Geo. Rennies) did not have my size and being pretty current and top end there were no used ones in the news paper (remember when that was the way to advertize stuff?). So I settled for the new version, admittedly a lighter and "nicer" handling bike but with out the fast back cluster or sloping crown.
This bike will be outfitted with mostly stock parts but I am not going to try to reproduce how it was when on the showroom floor. 35 years of seats, pedals and brake levers have changed my tolerance for the original stuff. My contact points will be those that I prefer. To the collectors out there that feel any thing other then show room stock is blasphemy I say "too bad, it's my bike. get your own". Well maybe not quite that cold sounding but after turning a wrench for 35 years I have very strong thoughts about bike set up and comfort and control are pretty high up there.
Again, thank you for the help in dating this bike. I'll document the rebuild and discuss the issues it has some time this winter.
