Probably could cook it in oven @ 500 degrees or so for an hour or so. Toroids are readily available from Amidon? Split a Ferrite and a iron toroid and you would have the difference in cores. Easily cut on a band saw. I'll keep looking for "C or U" coil forms. Your block diagram looks pretty right on, I'm trying to think of the simplest way to do the waveforms, make the PM fields, etc. His device obviously was a work of art! Could you possibly upload any other pictures you have?
Just had a thought looking at the scope shots. I live and die with the scope. Is it possible we need to consider that the start of a cycle is where the one complete wave goes negative and then crosses back over and goes positive and then turn the sync detector off and on at the right time in what is now the second half of the positive going wave, then the H bridge goes off and allows the "crap" in the coil/C core to integrate into the output. This makes more sense to me in that we unsaturated or drive it in that direction in the coil with a negative going wave/field (assuming a positive wave/field caries it past the knee in a positive direction) Then we remove the load for the small time allowing the VHV pulse to occur and when we turn the load back on when that pulse is between 1200 and 1700 V Peak, it twangs the core and magic happens as we turn the load back on.????? Just thinking. Again, your basic block I think is dead on.
Going to bed now going on 11 pm here.

The answer to that is actually pretty important, because it would tell us what is happening to the flux inside the circuit. If we get spikes back to the input, we'll know there is flux being counter-induced in the primary. If we only get spikes on the HV side, we'll know there is a one-way action and that the output portion is the critical part.
