I usually don't email the list with my ebay sales, but I have a couple of small items that are a bit different.
Weinman chrome top tube cable clamps excellent:
Shimano Dura Ace top tube cable clamps (stainless or alloy?) excellent -
maybe these are more common than I think:
My ebay name is yourselfworks.
There are other small Campy & misc. parts listed. Of course if you are looking for a not-too-expensive tuba or sousaphone, I am your man.
