I can't believe that this is all that important. We know that Tesla
never just plunked a whole formed, air core, fully resonant coil system
down in a single blast! Instead, he somehow or other had it mature
from his earliest iron cored, untuned, disruptively discharged system
(spark fired induction like coil) To his final demo system which was
all air core and resonant, sometime between 1889 and 1892-93. I feel
certain the iron core went away first and finally, the tuning crept in.
There is not real precise paper trail.
