Sounds like a capacitor discharge ignition. Does it have a low voltage battery? Transistors might be part of oscillator to charge cap. Might be a close cousin to the Electric Match.

Drawing is from memory, and that's not getting better. Each push of the switch prodeces a spark. The cap. probably around 200μF or bigger, spark coil like used in model airplane engines of the 1940's. I may still have it somewhere. Every thing in use now is piezeo.
