That cleaned up well! Congratulations! It's a beauty. Windsor is one of my favorite marques from the late bike boom era.

I suppose this would have been a competitor to the Motobecane Grand Record, which was IIRC also 600 equipped in that later incarnations. Kind of hilarious that this Windsor has Campy Tipo hubs mixed in with the Shimano stuff...

Wait a sec, did you replace the old Grab-Ons with new ones? Where did you even find them?
