Mystery solved, finally got a hold of elevator guy (lost his #) and the story was he bought the bike from a fellow mechanic who worked for Campy and was one of the mechanics for the Tour De France back in the day. Elevator Guy bought the bike from him, pulled all the Campy gear off it for a build he was doing. Installed all new Shimano (105) everything except wheels and cassette and sold it to me. I'm loving it and the Jeep hasn't moved in 5 days. And yes it is a 1982 720, and yes he did know someone at Trek. Thanks everyone for all your help.
