That is very true. However, all the transformer manufacturers (and we had a  
lot of them) seemed to do a lot of C cored transformers, and one must asssume  
that there was a sound logical technical reason somewhere. They also got  
used a lot in the higher grade professional equipment.
 
Wisdom of the English military? What wisdom? Plus the Treasury of course -  
from the early 1920s right up to 1936, military spending in the UK was on the  
basis of there being no war for ten years! What I do find interesting these  
days is that the military, here and in the US, have suddenly discovered  COTS - 
Commercial Off The Shelf. Something new! Pity nobody has reminded them  about 
the Hallicrafters HT4 amateur tx (AKA BC610) and the number of  
Hallicrafters, National and Hammarlund amateur rx's supplied during WW2!
