Teletype Model 19 (and Model 15) Demonstration

We demonstrate our fully restored Model 19 Teletype (from 1940) talking to a Model 15 Teletype (from 1930). This is a demonstration format, from the user operation point of view, to wrap up the restoration. The explanation of how the selector works is new; however, most features were already covered in much more detail as we restored them one by one through many previous videos. My excuses to the patient folks who learned it all through the restoration process, and might know most of this already.
