Scott 6T11 yoke question..

I'm in the process of trying to bring a Scott
6t11 back to life and have encountered something in this set I've never seen before.
At the end of the yoke which would be closest to the screen of the CRT there is what appears to be a winding of Rusty iron wore. Also there is a spring clip sort of thing sticking out, which is connected to the ground pin of the yoke connector so this would be to ground the aquadag. On the opposite side there is something that looks almost like steel wool sticking out. I have no clue what it is supposed to do. The horizontal, vertical and focus windings all measure exactly what the manual says they should, so I'm hoping it is good.
Any Scott people know what the Rusty wire is for? Possibly a magnetic shield?

I had some yokes that I junked a while back. I decided to take them apart so I could salvage the copper. One was similar to that in that it had just a bunch of steel wire around a core. I've been curious ever since just how that was supposed to work. Now we can both sit here and wait for somebody to tell us!

It wasn't too clear in the photograph. But my guess is it could likely be a magnetic shunt to reduce the scan width. Otherwise if it may have been used for focus.

The real early yokes had steel wire wrapped around around the yoke windings instead of the ferrites. I took a few of them apart and I discovered that.

The steel wire would be similar to the lamentations in a power transformer. But made small enough to avoid eddy currents at 15KHz (the horiz frequency).

The plastic yoke bobbin looks similar to the yoke bobbin in the motorola I rewound last winter.
