I happened across this scintllation detector at a ham radio fleemarket. It was orginally from Ukraine ~ 80's vintage perhaps. has anyone seen one of these before? Is it NaI:Tl ?
Was curious about it.

Yes, it should be NaI 40*40 with FEU93 PMT.
Not so big chance that it's working with good resolution, but you can try.

I'm asking about the pinout from the tube, not looking for usage in Gamma Spectroscopy as it is, as you say probably not in the best shape. Do you know where I can find a pinout for such a tube?
Looking to do a counting project with it.
