Seeking manual for old bench test gear

[Avery W3AVE]

Specifically a Jackson 650A "condenser tester," as these used to be
called. I'm guessing 1940s to early/mid-'50s. Looks sort of like a
knockoff of the Sprague Telohmyke series. I've looked and asked
everywhere--all the usual and less-usual manual sources.

Thanks, Ken. I did post there. No results so far. (Nor on rec.antiques.radio+phono.)
