Great videos Kevin!

I've seen a lot of TT-4s & TT-76s, but never seen them at 100WPM.

Looking at the keyboard, I think you have a "TT-4A".  Having the model 
number & serial number on the cover was convenient, but covers often got 
switched in maintenance shops. (Or maybe you have a TT-4C chassis with a 
TT-4A keyboard.)

We  have a TT-76B with a TT-76C cover (or vice-versa) and the wrong 
cover interferes with the character counter mechanism,  Took me a while 
to figure out what was going on, since it worked fine without the cover.

Have fun,
