Here are the measurements just taken, and compared to the speakers.zip information:
Field coil: spec 480 ohms; measured 469 ohms.
Transformer primary: spec 660 ohms, measured 656 ohms.
Red and White voice coil spec 1.25 ohms; measured 430 ohms (DC) - with one lead disconnected from transformer
What is the flat- wound low resistance coil under the field coil called? It's in series with the voice coil and the secondary of the output transformer.
