"There were definitely racing frames with eyelets in 1973, the PX-10 for one. Probably not many Italian racing frames with eyelets by then, but more likely in a French marque. . . . Hard to say without contemporary photos whether the actual team bikes of Ocana and company had them."
I happen to have at my desk the November, 2004 issue of CycleSport (brought in to share with a list member) that features a lengthy retrospective on Luis Ocana. Page 114 shows a partial view of the front dropouts of his 1973 Tour "Motobecane", and on 116 one can see the rears. Both appear to be standard 1010s, sans eyelets. I don't doubt that Jerry is correct though, this particular example aside.
