Guestimates from CST:

Cpri  = 0.15uF
Vpri  = 30,000V
Lxtra = 20mH
Fxtra = 86000Hz

Therefore Cxtra(tot) can be calculated at 175pF.  
The coil efficiency was probably 70% or less, 
owing to the salt-water capacitors.

Epri = 67.5J
Esec = 67.5 x 70% = 47.3J

Vsec = 735,000V (max, from Conservation of Energy)

735kV will easily jump 30 feet and more, given that 
Tesla ran at break rates of up to 1000 BPS!  
At those break rates, 400kV would probably have
been sufficient to produce the arcs as shown in
the famous photographs.
