Hi David:
When you say "Mercury went BACK to shellac some time in the mid 50s," do 
you mean for 78's or microgroove? I have no Mercury or Emarcy recording 
among many from that time-frame that appear to be pure shellac but there 
is that strange vinyl-ish material for the Emarcy jazz records. Was 
Mercury still pressing 78's widely in the mid-50's?

The majors began using vinyl for kiddie records around 1947 (earlier 
in the case of Cosmo's "Tubby the Tuba" in 1945) and Victor began 
pressing DeLuxe editions also in 1946 or 47. Decca put out a few 
pressings on plastic as well (Eugene List playing the Rachmaninoff 
2nd). I don't think there was much use of plastic for commercial 78s 
until wartime restrictions ended, but of course V-Discs were vinyl 
(except the ones Columbia pressed).
Victor put out the Stokowski "Gurrelieder" on its Victrolac compound 
in the early 30s. Aside from their use of the stuff on 33RPM Program 
Transcriptions, that's the only example I can cite of commercial discs 
on vinyl at that stage.
DJ pressings used vinyl in the mid 40s, of course (except Musicrap). 
Mercury and MGM seemed to have switched to vinylite (Merco-Plastic, 
Metrolite) in mid 1949, and a number of other small labels went along, 
while the majors stayed with shellac for the most part.
Anyone know why Mercury went BACK to shellac some time in the mid 50s? 
(Canadian pressings remained on Quality's vinyl-ish material to the end.)

What's the history of vinyl 78's? I have a small pile from I think 
the very early 50's, these are pop and country tunes. Was vinyl used 
for 78's in any mass quantities previous to when vinyl LPs were 
mass-manufactured? The "newest" vinyl 78's I know of are kiddie 
records pressed in the mid-60's. Aside from novelty stuff, was the 
medium used after the mid-60's?
Thanks for the coming history lesson!
