The measurements seem reasonable. Not sure about the resistance across the cord but in may just be an anomaly do to the digital meter reacting to the inductance of the primary and the line caps. Wouldn't give it too much thought.
Next steps in my mind would be to put the transformer back together and connect your dc volt meter across C-49 noting the polarity. Plug in all of the tubes and the spkr. Plug in the cord and turn it on while watching the meter. DC voltage should start to rise after a few seconds. Will peak @ abt 370v and start to drop to abt 320v as all of the tube start to conduct. If you don't see several hundred volts after it's been on for 10 seconds or so turn it off. Else bad things could happen.
Have Fun!!

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.
