If you found a speaker out of an 80, 81, or 610 they would be a suitable electrical match for your set. I think all of those have the transformers mounted the speaker's frame so they would have to be moved to the chassis.
Dc resistance of either the pri or sec of the opt isn't going to tell you much about it's plate load resistance when connected to a tube. Nor will it give you any idea about the turns ratio which are two key factors. If you know what circuit (tube (s) used) the transformer came from that can be a big help.

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!
