I think a display like that is used in the HP4275 series impedance analysers...
Hope it helps

Hi Robert,
Thanks for responding!
It would be great news if your module(s) could solve my problem.
ISTR that HP 1990-numbers are internal references for HP 5082 numbers.
I have placed a photo (not mine, picked from the 'net) of the module I'm looking for.
I'm looking for a functionally identical module with red leds and anodes on rows. Depending on your price, I'm willing to take a chance. I can measure and check colour and connections easily.
This is for a DIY clock that I'm building, using different vintage display modules, so I can modify things if necessary, except outline dimensions and colour to some degree.
Ooohh! Please post pics of that when it's done.
-Dave
