Most of newer flyback transformers have diode inside. This is reflected on diagram there. Of course, guy wanted quick access to resonant frequencies and the quickest stone age approach is by spark gap.


If anyone got spare wire and time, you may try to follow my suggestions while trying to replicate effect:
The wire diameter of current providing coil should be 4 times bigger than in choke. Also choke should be winded opposite with at least 4 times more total winding count than current coil(s). The connection over capacitor between them should be on opposite polarity(perhaps this is right one). Also capacitor should be picked for right capacity and right size and for large reactive power (no small caps) when making resonance in series. We are looking for making quarter wave resonance there and for making standing wave inside of air core transformer.

Hopefully this can help to do progress on the concept.
Cheers!

I don't object to the spark-gap. The gap is an inexpensive device to generate short pulses of current.
According to Mr Fourier, a short pulse is composed of many closely spaced frequencies, thus a spark-gap is a cheap device to generate many frequencies at once.

I don't object to the diode connected in series with the secondary winding of T2, either ...regardless whether it is built-in or an external component.

However, I object to the AC waveform applied to the primary of T2 where only PDC would be sufficient.
AC primary current with a diode on the secondary wastes efficiency by increasing ferrite hysteresis losses and joule heating as well as unnecessarily complicates the primary driver circuit, where only one transistor would've worked as well.

Generating many frequencies at once with a spark-gap, is a useful technique for exciting LC resonance without precise frequency tunning.  It resembles the Shotgun Approach.
It is not the most efficient technique, but it is certainly the cheapest and the easiest.

On the subject of the flyback transformer, what is that wire like thing running through the primary coil winding and wrapping over each end of the ferrite core?

With one transistor you need precise moment when to give impulse to LC primary resonant part. In that case I just got example what is working in Romanov's devices:

Supplying the primary of a flyback-transformer with AC does not change the pulse at the spark-gap in any way or any phase relationships compared to supplying the primary with PDC via one transistor.
Supplying the primary with AC makes no sense when a diode is connected in series with the secondary. Read it twice!

Also, when a diode is not connected to the secondary in series, then the transformer no longer works as a "flyback-transformer", e.g. the turn-ratio becomes applicable.


P.S.
The Romanov schematic does not have a diode in series with the secondary, thus this transformer does not work as a "flyback transformer" anymore.
