The SP-352 is a two-digit planar-gas-discharge
("Panaplex") display by Beckman
(formerly Sperry Information Display Division).
These displays were capable of being driven by another Beckman product series, either a DD-700 or DD-702 integrated circuit. You can read more information about them here. If anyone has a spare display or two, please drop me a line.

I'm looking for two spare displays, to replace flickering
displays in a Heathkit GC-1005 alarm clock.
The flickering occurs most often when the digit 1
(fewest segments lit) is displayed.

The display on the left was in use, on and off, for about 25 years. You can see a layer of metal has been deposited (sputtered) adjacent to the display segments.
The display on the right is relatively new, with fairly clean display segments.
I did manage to locate part of a display board. |
These scans are taken from a 1974 Beckman catalog.
