A friend of mine who is a radio/comms technician down south from here sent me this YouTube video.
It goes back to the 1970's when stuff was made by hand in the US.
Now, don't get me wrong, I am not trying to stir anything up here, but watching this video, I can see the skill that went into building this sort of equipment, some of you here may in fact remember or have worked with this very gear.
Here is the video (which starts off with an intro).AT&T Archives
