I have a few bikes with provenance, not all "fancy".
1938 CCM "Flyer" Six Day Bike ( I have a photo of the owner with it from 1947)
1948 Ernie Clements Clubman that I bought from the original owners son.
1974 Teledyne Titanium TRACK (1 of 2) that belonged to Canadian Cycling Legend Jocelyn Lovell. You can see him in action here

1986 Serotta built "Murray" . Probably a team bike as it had a number tab and only weighs 1720 gms. for the frame! I am trying to find out who it was built for but Serotta doesn't have any info they could find...
1989 Cyclops Track that was built for Canadian Olympian Kurt Innes. I have e-mailed Kurt and he said that it is built from 753 and was his point/sprints/practice bike (He raced pursuit/TT) and that he raced/rode it all over the world leading up to the Worlds and Olympics in 1990(?)
