An IF transformer is difficult thing to rewind and make it work properly. The type of wire, the distance between the coils, how it's wound, and the amount of Q of the coils are all factors that determine the IF transformer's performance.
If the rewind looks like it's hand wound or spun on a drill I would look for a replacement 175kc transformer. They were popular from the '30s-50's so they're not hens teeth.
The resistance readings don't really mean anything in this case. It would just tell you if the coil is open or not. Your probably looking for about 20-30 ohms.

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!
