[R-390] Maybe useful?

Very useful.

RCA and later VIZ made several models of those.  Used to use one in  
the radio shop.

Looks like it could  be an isolation xfmr with voltage taps but not  
familiar with this thing.  Maybe some of you folks might be familiar  
with it.

Not mine.  Don't know the seller.  Just passing it along as something  
that could be useful for those leaky power line filters...
