 I bought a good used original from Fair Radio for $10. It's still working fine.

 Don,
  The one from K5SVC was linear, the one I got today is a RV4SAYSD502E from tedss.com but pricey at $54.

Jacques found a couple more at tedss that are cheaper at $39 if you do not mind cutting the shaft to length.

And larry found Precision Electronics Corporation had some, part number KB5021S28 but is waiting back on a quote for pricing.
