One of my minor sadnesses is that about 4 years ago I bought a nearly perfectly-preserved Guerciotti with a full 1st Gen Super Record Group, for about 400 bucks. I still have some of the parts, sold the frame off long ago....and, stupid me, I sold the front derailleur with another bike--those being the days before I realized what I had. The 1st gen front SR derailleur had *four* perfs in the cage. Try finding one of those sometime.
<sigh>
