A friend knew a guy who knew a guy... At the time IBM spun off a lot of little cottage industries to handle stuff that they didn't want in house, in some cases because of paranoia about being a monopoly. Anyway the guy in question was operating his little ferrite business out of his garage. I drove down to his place in the outskirts of Kingston. As i recall he gave me the cores as a sample to avoid paperwork. And I was on my way to a CDI! I've looked at enough of those projects that when I see some strange component or parts with values that aren't common I realize those were whatever the author had laying on his workbench at the time rather than the result of careful design. I still have a collection of ferrite toroids, air variable caps, and so forth from when I was messing around with radios. You can bet if I design something it will be using them. Good luck finding the exact part in 2025.
