To lower the frequency of the circuiut while its running I have two ideas. 
First you could use an extra tuning coil like some people use, but make one 
so a motor could drive it while the TC is on. The problem I see with that or 
just adjusting the primary is that the area where the contact points move 
might spark when its adjusting. Another thought I had was one of those 
variable air capacitors, perhaps with oil instead of air, and have that motor 
driven so when the coil goes on you can adjust the cap from no capacitance to 
full capacitance. Would a variable air cap have enough capacitance to make a 
large enough difference in tuning?

<< Steve's observation of the streamers growing when the coil was tuned
 a little to the low side seems to support the theory. I don't have a
 coil I can experiment on yet, and would like to know if slowly adding
 turns as the coil fires could extend the existing streamers...
