I say split-bobbin.

Yes, split bobbin - enhancing insulating between primary and secondary.
I've used those Triad 'low profile' transformers in some projects due to the ability to fit in tight spaces.

is that the same as R-core?

Basically the same, separate lams for the split-bobbin vs a coil of steel like a toroid.

Laminations are stacked U-I rather than a continuous wind like a C or R core.

I agree this is most likely a U-I. The following link shows a C core and how it's typically used.
