Here are the pics. I didn't take one of the back of the jig but it really isn't much special to see. Just an empty cabinet basically. The meter was a later add-on offered by RCA; likely came after the xray scares of the late 60s? There is a note in the back that states that there may be vertical foldover problems when using with a rectangular crt chassis. This jig was used quite late; he is now using a fairly late model Toshiba as a jig.
In reference to wishing for cataracts, this tube does not appear to use a seperate faceplate so no luck
The biggest problem with keeping it as a jig is I don't know where I would put it. No room for a monster like this. I have a set of extension cables that another repairman gave me, which would allow practical servicing of some chassis' outside of the set.
