Hi Les !
I've just checked a French book of 1947 vintage.
My thought is that Kodak (and many others ) had a boost using the 
knowledge German people had, and get as a reward, the know how to 
improve some "well known" optics gained by the Zeiss, and Schneider.
In my book, the "new " (in 1947 ) optics from SOM, Boyer and al are 
copycats of pre war Schneider or Zeiss optics.
My opinion is that Kodak, and to a lesser extent the Japanese get access 
to the very same information  French and Great Britain opticists had at 
the end of the war when people could go into the German optics 
secrets... Be it glass making secret or technical knowledge in centering 
or polishing the lenses...
I remember my grand father telling me he has seen coated German optics 
_before_ WWII. When had Kodak (and others) begun to coat their optics ???
Of course, this is just a thought, so I may be wrong... Don't take it 
for granted ;-) I was not born at that time ....
