Hi Lee
I can't see all the details in that picture 1 but it looks to me like the thin grey and yellow wires to the left, which pass through the frame are the VC connections.

Normally these would not be connected to the field winding but I can't see from the picture with certainty that they are not tied to it at the terminal strip.

There appears to be a heavy red and black wire coming out of the right side of the field winding and I can't tell exactly where those go. Can you inspect this in more detail?

Starting at the left as terminal 1, it goes to the yellow VC wire, terminal #2 appears to be connected to the black VC wire.
I can't see if the black and red field wires also connect to that or what they do. As the output transformer VC winding is floating, to save wire, it could be common to the field but that would be unusual.
Terminal #3 is the black field wire and #4 the yellow field wire.
Can you give the black / red field wires a closer look and conform what they do?
Can you also lay a ruler across that "U" magnetic return and give me an idea how wide that is (for my own curiosity) and let me know what that speaker is out of.
Best,
Tom Danley
