"it was manufactured as a 1193 but named E1148 by Hytron"

How do you know this? I don't have the Hytron data sheet, but I found one from the "Ministry of Supply (S.R.D.E.)" for the CV6. You originally referred to this tube as a "1193/CV6/6S5S," and said the heaters all draw 300mA. However, the CV6 data sheet states 200mA and Gm of 2250 to 3750. Honestly, there are too many contradictions in all this for me to make sense of it.
