Fantastic 5061 tube photos. Museum quality. Thanks for sharing those with all of us.
Four coil wires makes sense, but...
1) The small coil around the beam line looks like the "LF coil"; used only for testing. A brief mention here:
2) And the parallel wires around the cavity look like the C-field winding to me. Perhaps you can trace the pins / wires from the outside to the inside, either by inspection, or with ohmmeter, to verify this. I'd do it for you but I'm not near a 5061A right now. In fact, you can trace the other wires too (e.g., Cs oven heater, hot wire ionizer) while you're at it.
Unless yours is a high-perf 5061 tube I wonder if the degaussing coil even exists. Did you pull it from an option /004 frame? Check if there's a separate pair of degaussing wires coming from the tube and heading to the rear panel of the instrument. That would make a total of 6 coil wires.
Corby will know all of this for sure.
