Before wasting time on this, de-rivetting the step up transformer
mounting etc.
Input side measures 5Mohm, HV output side 12.7R, but looks like a
standard mains transformer.
Would this be a purpose wound transformer or an off the shelf mains
transformer that could be replaced with similar, if so what sort of
voltages and which way round ?

In the ones I built I used a standard car ignition coil ! 12 volt
battery and 1 pulse per second into it !
