Or is the coil burned out? That's the most common failure mode.
There's a guy up in Cleveland or Akron at Play Things of Past who has a storehouse full of parts and junque. He may have the right speaker.

jeyurkon, I'm a bit confused about your post - I'm with you to the 3.2 ohm voice coil impedance - but field coils varied from 500 to several thousand ohms impedance. Without knowing what the radio used, substitution of a choke for the original field coil is dicey, isn't it?

That's why I said it was an educated guess and didn't want to be held responsible. I looked at various Westinghouse radios of the same year and they all seemed to be a little over 300 ohms.
But, since he has the field coil he can use it. Or, he could measure it's DC resistance and see if the choke is close enough. I should have read his response more carefully because I had missed where he said he still had the field coil.
One thing we should probably be asking is whether any other restoration has been done like recaping it. I hope I haven't overlooked that information somewhere too.
I'm new to this forum so I don't know who's an expert or novice.
