HP nixie tube module information needed

Probably my best find at the recent Hamvention in Dayton OH was a
stack of nixie tube modules made by HP. In retrospect, I wish that
I had purchased the whole box of them, but I hopefully have enough
to at least make a clock.

I have two variations on the modules, the part numbers are:
        HP 05212-6016 series 648
        HP 05212-6003 series 415
They both use Borroughs B422 nixie tubes and look like they may have
an integrated HV supply of some sort.

Here are a couple of pics for reference:


I would appreciate if anyone can tell me what HP (or other) instruments
may have used these modules. I would also like to find a schematic of
the module if possible.
