I actually did an advanced search this time and came up empty. I'm trying to determine what seat post binder bolt was used on a 1974 Raleigh Professional. I don't think it was a Campy bolt because the "ears" on the seat tube have a slot cut on both sides, closest to the seat tube, to accomodate the "wings" on whatever binder bolt was used. I haven't found any Campy binder bolts that have wings. Could it have been a Raleigh binder bolt of some sort? Also, there are no threads in the ears.
