As I was browsing this evening, three Campy "steel" rear derailleurs from the early 60s presented themselves. Funny thing is that NONE had the steel pulleys with ball bearings that I'm accustomed to seeing. Two had what seemed to be later Campy plastic-with-bushing sets, and one had off-the-wall toothed pulleys. Did the original Record ever ship with other than the steel pulleys with ball bearings? Mine have the little protrusion to anchor the slot for the cone, and that would have to be removed for other types of pulleys.
TIA.
