I stuffed around a bit with it, but unless the resistor on the "base", if u could call it that, is at least a megaohm, it didn't seem to oscillate, but I could be wrong, how come?
And the model for the spark gap has a resistance? Why is this? I didn't think spark gaps would have resistance.

Air has a natural breakdown voltage. When the potential is high enough, an ion trail is created that allows current to flow. That current will flow as long as the potential can maintain the ion trail. This is the same process as atmospheric lightning. There are things you can do in the construction of the spark gap that will increase the probability of generating a spark.
So how would you tweak the "holding current" in real life? The only parametre I know would be distance, and then that would just select the breakdown voltage.
I'm doing something with some dielectric matter and electric fields with it, (Im causing decomposition.) And I think if I had a spark gap oscillating with it, it would improve things.
<edit> or is it a matter of just keep on adding resistance till it oscillates </e>
Ive got no idea, all I can say is its probably useful having a retriggered lc oscillator at super high frequency, that would go into terrahertz, one possible way to do it.

... it has to do with Nyquist theory and convergence errors when the exponential rise time approaches sample step time, and this appears as ringing. The arc conduction risetime is very fast with negative resistance gas tubes or spark plugs. In LC circuits ringing occurs when the current is switched off. INCars they use ~ 50 kohm carbon wire to limit the conduction current.
