Neat! I saw that pic and commented already so I won't do that here. Neat setup though, and cool you plan to try to fix it!
I think vintage clocks are neat, but I'm not as interested as I am in lighting. Are you really into clocks? My closest thing would be vintage clock-radios and vintage analog-tuning stereo tuners/amplifiers. I'm sure I've mentioned the 1978 JVC my godparents have and I'm going to try to get.
I like your passion to fix things that aren't yours...I'm sorta the same way.
And is there a way to make an outside call with the phone handsets on that Simplex system or is it JUST an intercom system?
My old elementary school, built in '88, had synchronized clocks but only the clock and speaker, not with the phone or light switches. Now you've got me interested in PA systems/sychro clocks!
It'd be cool to see a system like that with a AM/FM hooked up to that...preferably a vintage tuner of course!
Oh and remember our discussion about fluorescent lights in kitchens? Well tonight at a party at someone's house they had either /950 or daylight (I think it was daylight). Pizza looked unique under that color...cheese looked yellowish, not orange! I thought of you, though, as soon as I saw it!
