Hi Ray,

I, too, have been sort of struggling with the same question for some 
years now. I think of the terms 'phenolic wafer' socket, 'battery' 
socket (as these were normally used on the old radio batteries as you 
mention) and 'wafer type socket' when dealing with these. Two or three 
layers of 'laminations' of phenolic sheet which was punched to form is 
the construction. So, maybe 'laminated socket' could be a search term? 
They were cheap compared to molded Bakelite or, especially, ceramic, so 
worked out well for the consumer electronics of the 60s/70s and back to 
the 30s when 'cheeply made' was important to be competitive and 
reliability was not much of an issue.

HH Smith, Cinch-Jones and Keystone Electronics may have been one of the 
original suppliers of these as this is the type of thing they would have 
produced. Possibly Amphenol, too. Maybe on an OEM basis so not often 
available in supplier catalogs.

HTH!
  Regards,
