I do need to look at several of the decoders to nixies they are acting

resistors around the neon bulbs?
Paul,
The photoresistors are on a ceramic hybrid - they put many resistors
on one plate to make the mechanics easier. Being HP, they could do
that.
Here's a website with photos of the optical assembly.
