Hi Tom,
I am not sure what you mean by "At some point don't all seatposts have limit lines?" What do you mean by "point"? Do you mean point in time, or a point of location on the post? In either case, Campy didn't stamp limit lines on their seatposts until the later '70s, with the introduction of the Nuovo Super Record (2nd Edit.) seatpost. So therefore, if your seatpost has a limit line, it would have to be a 2nd Edit. SR/NR/G.S. (assuming we are talking about classic Campy, not the more modern stuff from '84 on).
