Last spring I was in Oklahoma City. I flipped thru a website full of things to see and one was the Oklahoma Museum of Telephone History.
This ended up being a great tour. It is located in a room in the AT&T building and the guide had worked his way up through the ranks of Southwestern Bell. He was knowledgeable and entertaining.
I shot this video showing the mechanical dialing system in operations. I figured I’d stick it out on the web, in case any one every goes looking for such as thing.
