I scraped away part of the brown ring, which was a wax like material. Whatever is under the wax is NOT metallic and a magnet does not attract it. It think it is just a recess in the coil bobbin. The magnet, if it belongs there, would have to have broken in half in order to go missing! Else someone removed it.
I assumed that it should look something like the photo (Shadow Meter Bobbin) in etech's thread on Shadow Meter Coil Rewinding.
