I once (197X) had an alarm clock w radio that collapsed (transformer) and I
salvaged the green display and clock circuit hoping to be able to replace
the transformer in any way, but it all was ditched a few years later, but I
still remember I studied how to drive the display and by changing the
filament current it was possible adjust the tube's brightness.
Now I have a clock IC and four ZM1020 and am prepared to make me a(n)
(alarm) clock. Besides I have much more experience from high voltage today
than I had 79+ years ago.

Loads of generic info out there on these - you should be able to
identify the heater with a multimeter.
Outermost two pins are the filament.
