Default Sylvania R1131C octal tube ?

I got a couple of the subject tubes which are supposed to
be "glow
modulator tubes". Best I can determine is that the light
output will
vary with current but I can't find data sheet googling.
If anyone has
pinout and/or data I'd sure like to see it. I think it
might be a mid
1960s item as my 1957 Sylvania manual doesn't show it.
thanks
