Horizontal efficiency coil concerns

[Tubejunke]

I may need a horizontal "efficiency" coil for my 1964 Zenith 5111. When I found the set there was no HV and the H. Oscillator tube plate was glowing red. I replaced the voltage regulator tube and the HV rectifier and had a raster. I just happened to notice on a visual inspection that this coil's winding end moved when I pushed lightly on it with my finger. I think that it should be rigid in order to be accurate, but I could be wrong as I don't know whether the mounting portion is just broken and would not effect the circuit, or if the actual inductor winding portion is loose.

I fear the latter as it seems springy to the touch. That could be the wiring. At any rate, it might be best to replace this if I need to and can find one. I know that all issues horizontal are critical in these old color sets which I am by far not an expert on. Any advice and/or help here would be greatly appreciated. Thanks in advance!
