OK,.. here we go:
(Sorry about the awkward hand positions, I was going for clarity, not comfort.
And so so sorry to everyone on dial up. I don't know a better way to demonstrate this.)
To thread this machine:
Step 1: The book says with two hands, slip thread horizontally between tension discs from the top.

Step 2: Book: With Right hand, lead thread under thread guide on right side...

This is what it will look like when you've lead it under the guide.

A further back shot of that right side threading. Note too on the left that the thread is on top of the spring.

Step 3: Book: And with left hand, lead thread over spring and under guide on the left side.
It's hard to see, but a slightly toward the back of the machine motion will hook it under the guide.

Step 4: Threading the rest of the machine (over the hills, through the woods, etc.)

Step 5: Threading the last part of the upper thread.

Completely threaded.

Now, this is what the machine looks like in "sewing" mode:

And in Bobbin winding mode:

If you look carefully, you might be able to see that pushing the lever to the left made that portion under the bobbin case rise up a little. That's important for bobbin winding mode.
To take it out of bobbin winding mode, close the slide plate.
