I have found out why the section 5.5s are missing - in an amendment sheet dated 1950, it clearly states that Section 5.5 is to be removed and discarded.
So did they decide not to bother with gamma correction or were they able to operate the Emitron tube on a suitably non-linear part of its transfer characteristic rather like operating an Image Orthicon tube on the knee in its transfer curve?
