I seem to remember that Campag had rubber seal cups bac in the shadowy past. One of the guys wrote me and said the rubber seals were on later mountain bike groups. I remember those, but I.m thinking of '60's. Might be I confuse them with some of the Japanese ones. If so , my apologies for faulty memory. I recall that the stuff as trickier to install as one had to lube and slide the axle back and forth to not nseat the seal . It took a different "feel" to adjust the cups properly, but one learned quickly. Back in the late '50's and through into the "70's, we mixed and matched many spindle and cups untill we got the mating we needed for chainline and fit. Not everything was available all the time so we made do. Shops were around longer and the mechanics had better experience by and large, so we'd see some clever stuff and did some ourselves, too. The concern was to get the people out riding, The 101% collecting/restoration was not so critical yet.
