Dang- I was afraid someone would ask what "Very Early" meant! I can't answer that, but I can paint a picture for everyone, and maybe that will help in dating it.

I have a NOS Campy Record road crankset that is 151 mm BCD, and comes in a box with a yellow flip-open cover with a blue line drawing of a Campy crankset, and the bottom part of the box is blue.

The crank says, "Campagnolo 9/16" x 20F." around the pedal hole. It is a 49T/52T. The bottom bracket that comes with it has a spindle that says, "68-SS-120 Con Sfere Da 3/16" and the cups are BSC and say the say the same thing w/regard to the balls. The spindle has pressed on races that include a squared shoulder inboard from the bearing surface.

The paper Campy tape that secured the box closed originally has the old-looking wheel/wing/QR logo.

So, what date is this?
