Who on the list can provide info (see ebay link below) on this special Campagnolo umbrella pump clip? It looks standard except has an aluminium ring just inside the the inner points of the umbrella section. This is the second one I own. One came with my recently purchased one owner 1974/5 Raleigh Team bike and then I just recently purchased this one. Any comments on what the extra ring was for, when they were sold, what they came on, etc. is greatly appreciated.
If the link does not work, type in the ebay number in the "search" box and that should lead you to it also.
Thanks to all who respond,
