In order to know this you need three data points to be sure; 1) The highest Neon Temperature. 2) Along with the lowest Transistor Temperature. 3) And the lowest input current.
When all three are present and you can see different spots throughout the tuning range where all three did not line up, then I might say you have indeed obtained running with a 2222. I must say though, I never have obtained (correct) tuning with a 2222. What you do get is a HV of around 108V to 127V that results from the L3 inductor, very similar to the collapse of the field in an ignition coil generating a HV by being dissipated over a much higher resistance during the collapse.
Anyway its just splitting hairs anyway, two side by side would be hard to tell apart until you touched the bulb.
