So who has the oldest Daily Watcher?

I think this was touched on in other threads, but I am wondering who is watching the oldest set as primary. I don't mean having a vintage set hooked up that you watch somewhat regularly, I mean the MAIN TV in the house.

To open the discussion, Len Horowitz in LA has a CTC-4 as his daily (and only cable-connected) TV. I have the 1972 Zenith 25" set, which we watch every day, and is the only TV connected besides the smaller bedroom set that we use to go to sleep by but seldom watch a program on.
