I have 6 individual (remaining from bulk packs of 5) NOS Campagnolo derailleur "bottom bracket" clamp-on, double cable guides for sale at $10 each, plus delivery. I believe the catalog item number is 626/a. They look exactly like any one, on any bike from the 60s and possibly into the 80s, but I can supply photos, if necessary. Absolutely perfect. First come, first served ... thanks!
