I only have a few odd things to offer up, but I'll post them anyway:
Schwinn-Approved Huret derailleur - I recall it having some issues when I pulled it off an old 1967 Schwinn Collegiate 5 speed, but I didn't really bother playing with the adjustments before I pulled it because I already had a replacement.
SR Apex left crank - I only have the left side because it came on a frame I bought, but it's in pretty good shape. It is 170mm and from the early 1980's.
Suntour braze-on downtube shifter, also left side only - This came off the same early 80's frame, again missing the other side. I should have most if not all of the washers and hardware that came with it.
If I find anything else in my parts box over the next few days, I'll post it up.
