Accidental Oscillator (Electronics)

[Dig_Gil]

I was playing around with LC tank oscillator ideas when accidentally an oscillator in Falstad's circuit simulator happened.
I've tweaked the values of passive components to give the nicest waveform. It makes sort of a sawtooth wave with a double-bent back.
I don't know how it really works and can't identify it as known, common, tuned circuit oscillator. I'd be grateful if you had a tip on that.

Evaluation is essential for tuning components to achieve the optimal waveform and for electronic creativity to be realized effectively.

Looks like a hybrid between a relaxation oscillator and an LC tank, possibly with regenerative feedback. Not a standard type like Colpitts or Hartley, but definitely a cool accidental find—those waveforms hint at blocking or multivibrator-like behavior.
