Are they hard to come by, I like to have them for historical reasons I guess owning a bit of history of shimano deraillers. Any input would be appreciated, thanks for your time.

i have a 1981 Schwinn World Tourist with a 10 speed Positron. The chain ring freewheels, not the rear cog. You can shift while not pedaling as the chain is always moving. I ride this bike daily to work and back, and it works wonderfully, but it does shift better if you dont pedal while shifting. As easy to shift or easier than anything from that era, including the best Campy.
