Yep, found a few.
This one must be the old fashioned bi-metallic starter. When the power is connected, the lamp is cold and has high resistance, so all the voltage drops on the starter and it opens and provides high voltage to the lamp until its resistance drops so the starter closes again and now the power is supplied via the current limiting choke. The only thing I don't understand is how is the high voltage generated as there is no multiplier. Perhaps those kinds of bulbs only need the mains voltage?
