Have you phased it out to find the windings and ratios? A little
common sense here can usually answer these question.

If it has a winding that when energized at 110-120 vac gives some
rational voltages on the secondaries such as a HT winding and 6.3 0r
2.5, 5 volts, you probably have a power transformer.

You see a lot of single voltage filament transformers, with or
without center taps on secondaries, that are Kenyons. Also modulation
transformers. Those have multiple taps on primary and secondary
usually, the primary being center tapped.
