These are unobtanium in the pinball community. You might want to see whether you can get a good price for them there.
I'd reduce the filament voltage a little. It shouldn't be possible to see the glow easily. Maybe faintly, in a dark room. Actual voltage will depend on filament length. Anode/cathode I'd normally use about 15V but less will lead to longer life. The phosphor on the digits tends to burn with exposure and as usual this is particularly noticeable if they're left static. Schematics are available for pinball machines if you can identify a display of similar size.
