This is a 3 phase primary, 3 phase (times two with 30 degree shift) secondary. It is delta/wye-wye. I think that it must look very much like the first image posted, but can't say for sure as the nameplate has info. The main thing I can think of is that both sets of secondary taps are 3P/4W wye.
I know almost enough about this type of transformer to give me problems.
