TV Typewriter Cover Unit location?

[Brad]

Hey there,

 

I'm currently working on a replica of Don Lancaster's prototype TV
Typewriter (pic here:

that appeared on the cover (with the more refined keyboard) ended up?  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
