I have at least two different examples of the red slug oscillator coils. One was purchased in Japan and is Toko or Mitsumi ( will need to dig it out of my parts box to say which exactly). I desoldered the second oscillator coil from a junk IC-based radio hoping to use it for my projects, only to find that it has a primary coil winding and no secondary coil at all. I never knew that such variations existed and am not sure how it actually works.
