I'm sure you're right.

However, a coil/capacitor is not a model or analogue of a
spring/damper system. It was discussed extensively at the time.

I am not sure I understand your response. To be exact a "spring/damper" can
be modeled as a coil/resistor. For resonance to occur you need a
capacitor/inductor, or mass/spring. All components of either mechanical or
electrical circuits require the solution of the same simple differential
equation, such as i = C*dv/dt etc.
