TV Typewriter Cover Unit location?

unique keys? I am not sure of that Unless he lettered in CTL looked like weird Mohawk data sciences keys or something.... I have seen this type of keyboard before... or some other place in a scrap environment post 1799..... Ed Sharpe archivist for SMECC In a message dated 10/12/2015 10:01:15 P.M.

I've asked around, including Don and nobody seems to know where it got to. I'm also wondering if anyone knows a source that might have the keytops that unit used or something close (I understand they were made by Mechanical Enterprises). I've enough parts here to build two or three TVTs and I thought after I get the prototype replica done I might go for the cover unit, esp. if it no longer exists anymore. But I understand those keytops were kind of a one off deal for that article. Thanks!! Brad
