48 should be the output transformer. You would want to check the primary's continuity. This can be achieved be measuring the resistance from pin 3 of either of the 42's to each of pin of 2 of each of the 42's. Should see something like 2000-3000 ohms. If it measures 100k or a Meg better add it to the list.
The K speaker is a 7 3/4 (8") used in the table top or B (baby grand cabinet sets). The H speaker is a 10 1/12 speaker used mostly in the consoles. Some console used both that's why they're shown in the schematic. From the picture it looks like your set uses a single H-12 speaker. No worries. I did a little looking and found the the K-6 and the H-12 are the same electrically. That's why they share the same output transformer. Physically ones bigger than the other. I think you measured the field coil and not the voice coil as it should just an ohm or so.

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!
