I'm also wonder about your looking for a "friction" derailleur since all derailleurs will work as a friction derailleur.
I know the GS, was never impressed with that sort of action. But it's a possibility. I'd be putting it on an '87 bike.
The reason I mentioned friction was so that suggestions wouldn't be limited to indexed-only.
The real point of my question was to learn about models. names, shifting quality, etc. "Any long cage" could apply to half the Shimano RD on ebay. I have no idea which ones shift well, which would be period-appropriate, which would be road-bike vs. mtb. That's a time period where I was not following bike hardware. So except for appearance they are just so much "stuff"
AFAIK.
