Hmmm...
I would say that if the 6-S-152 speaker you parted out was originally painted copper or gold as were many Zenith console speakers, then the last one you photographed is likely the right one for it. Although I find it odd that it would have one voice coil lead on one side of the transformer and one on the other, it is still usable. I think the DC resistance it shows (528 ohms in your photo) is probably correct for a 7K impedance to voice coil transformer, also.
Please measure the secondary (voice coil winding) resistance and let me know what it is. I do think the last one is probably the right one. The 921 ohm reading of the first one's primary seems too high to me.
