John:

I think you are among the "youngun's" here. Sorry.

Funny about the 206 selector. I scarfed a 207C intercom from an abandoned building when I was a kid. I got frustrated trying to make it work, so I stripped it down to the wire-wrap connections and did them on my own. NO, it never really worked right, but it sort-of worked.

Sam, it sounds like we are both addicts. Come on in to our "meeting".
