Only two questions today

^^I screwed the pooch earlier^^ For sync you need the no1 plug otherwise the pattern won't know "where to start." The old Allen we had used what MAY have been an inductive device for the no1 plug but it used the forementioned capacitive device for the n1 sync. It also had a "points" (dist neg) connection to see the primary pattern.

I'm not sure whether inductive would work in this case or not. "It might be" that differences in plug wires, resistive or not, wires or plugs, etc that a capacitive pickup works better. I've only worked with about 3 old scopes years ago and they all used a cap pickup for the secondary pattern.
