Does anyone know whether there was a correlation between years of production for Colnagos and the producer of the drop-outs? I have what appears to be either an early or mid-seventies Colnago with Campagnolo drop-outs and I have a mid-eighties Colnago with Colnago drop-outs. I have also seen them with Shimano drop-outs, but I am wondering in particular about the Campagnolo-Colnago use of drop-outs.
Thank you.
Cheers.
