Seeing how the question was asked on this thread and it is chassis related, I will none the less answer it here.
On your speaker, you should have 4 wires going to it from the chassis. Your set has the speaker output transformer under the chassis and not on the speaker. (saves some wires). Two of the wires go to the speaker voice coil. The other two go to the speaker field coil. The field coil is used in the B+ power supply for filtering and the speaker for supplying a magnetic field so the speaker will function. No permanent magnet on that speaker.
As for tackling the project in "reverse" order I will say most going through the chassis first. Perhaps to see if there are any show stoppers that would indicated it would not be financially reasonable to restore the set. Makes no difference to me if you do the cabinet first. I will say the chassis will be a bit more of a challenge. Getting the cabinet nice will no doubt give you some confidence.
