Actually, not all of the World discs were vertical.  Many were also 
available as laterals.  The verticals had red labels and the laterals 
had green labels.

Until the mid-30s they also offered their pressings on either stiff 
vinyl or very floppy clay colored acetate -- real acetate, not 
misidentified lacquer -- this is the reason why so many radio people 
incorrectly call lacquers acetate.  You need to occasionally check the 
World acetates to make sure they don't smell vinegar.  I've never come 
across a clay colored one that smelled vinegar but I have smelled it on 
clear and blue ones.  (Lacquers are cellulose nitrate, by the way, and 
if you call them anything but lacquers you could call then nitrates.)

I have a pair of test pressings of a 1935 program, one a vertical and 
the other a lateral of the exact same "take" of the program.  The 
lateral is very good but the vertical is FANTASTIC.  Especially as it 
reaches the outer edge at the end of the program, the sound quality of 
the Graham McNamee announcement is breathtaking -- and I am no fan of 
McNamee.  World and WE was claiming 13,000 and 14,000 cps. top ends as 
early as 1932 and 33.
