Oh dear lord - that is the closest we’ve EVER gotten!! The clip and the button are exactly right and the body seems to be the same although I don’t remember that much writing. However, I definitely remember a S series style cone. What’s weird is that I drew a picture of it years before I ever saw an S series or even knew they existed, and it was virtually identical apart from being that much narrower than the current S series, cone (which I now own) and can attest to the narrowness of the original. Of course, my drawing of the cone could be just a memory (or drawing) aberration and perhaps my mind has become convinced that’s what it was especially once I discovered that the S series matched it perfectly.
Thank you, thank you thank you @Mecha - you have gotten me closer than I’ve anybody has in the last 20+ years!
Also, thank you to everyone so far that has helped me… I hope this information moves forward the help that everyone’s giving me to finally identify the model I am seeking.
(and hopefully this works towards displaying to everyone that has helped me that I am not crazy and that my description was pretty darn accurate!)
Certainly is capable of being put to use for any purpose that a pencil can tackle.
