Mike, No spkr here it's used in a signal generator. Pri is the feedback winding for the tone osc. Secondary couples the tone to the buffer/amp tube tube to achieve modulation.
Did see an inexpensive one at AES but not sure if the secondary winding can handle the plate current from the buffer tube.Primary is good for 10ma which is fine for the audio osc side. Also the DC resistance can vary depending on the wire size. You can't count on the pri and sec being wound w/the same size wire. Resistance means very little when looking for a replacement transformer.

When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.

Now I think I've got it!
