Yes, very low frequency. The one I built in the 50s oscillated at between
0.5 and a few Hz, depending on how one tweeked the capacitance, as I
remember.
I searched the web for something about lamp-R L C circuits and found
nothing. Maybe Bill Beatty has something in his amazing files.

I think that the heating/cooling response curve of the bulb may
be a couple of orders of magnitude too slow for anything except the
lowest of oscillations. I seem to remember a kid in my class back ca
1960 who tried, unsuccessfully, to build a filament-modulated
amplifier. If one could tie down the response curve time constant for
the bulb filament, in might make an interesting simulation.
