I know I haven't. Very interesting.

I haven't seen one. I thought I saw some talk on one of the List Serves about this dial, or one like it not long ago. I can't remember what the gist of the discussion was about however.
Never seen or heard of it. Guessing that it's going to be expensive.
Very interesting design.
Looks like it was on a late 70's candlerstick or repro 202.
