A very pretty coil.

about 1000 turns on the 2 1/2" x18" secondary, 5 turn primary tapped 
down to 4 turns. 18nF primary C.

I like the three pipe gently blown gap (because I use one identical to 
it!).. for low power coils, I've had good luck.. it's more easily 
adjustable than a two pipe gap, it's only two gaps, so gap losses are low..

That's a fairly high current low voltage NST compared to typical 
practice here in the US (it's like a 12kV 60 mA in terms of power..) so 
you might want to change the primary L and C a bit to match your 
transformer, while keeping the resonant frequency in the same 
ballpark... (bigger L, smaller C)
