Reno:
In the split buss, delta panel, was the top (3 phase) section barriered from the neutral buss?? I personally have not seen a split buss panel in many years.

I recall coming upon a attempt at 120 volts, from a 3 phase 240 delta, 3 wire, by a rocket scientist using the ground for a neutral, as this was 'power panel' only!
