The single-turn winding is as shown in the circuit diagram the eht filament/heater winding.
The primary would be someting like +V to pin1 and one of the pins 2,3,4 or 5.
I would remove the single-turn winding and wind a new primary on the now empty core.
Start with 5 + 5 turns of about 1mm copper wire.
You can use this flyback in a conventional manner BUT
- a more modern high power split-diode secondary flyback transformer is easy and cheap to come by and would give 'better' performance.
- ac flybacks are highly prized by voltage-multiplier experimenters.
I would most likely use this flyback to drive a Cockroft-Walton/Villard multiplier
and use that to power a Marx generator.
OR in a conventional 'flyback' configuration with a new primary driven by an igbt and 555 powered by a 12V battery for portability/safe experimenting.
In any case start with your own separate primary winding just in case you accidentally damage the original windings.

One reason for keeping the single turn winding for futur use is it provides an isolated signal representing core flux that is insulated for 25 kV DC. All the other windings are an autotransformer.
here are the flyback testers missing from my prev post
