That is indeed an interesting specimen.
The pickup looks like the same type found on those early Eleuke/Teton steel string models that never really hit off.

Few observations and hunches:
-No visible adjustable truss rod. I have tinkered with ukuleles with and without truss rods - and on a steel string, I find that they help enormously in an intricate setup.
-Those pickup switches are configured weirdly.
Instead of having a pickup selector switch on a conventional 2-pickup electric guitar or ukulele (neck, both, bridge), they seem to have On/Off switches for the two pickups. Quite a strange and archaic way to configure... though I think I have seen some vintage design guitars done this way (such as the original Hofner bass?)
Given that it's a rather cheaply made instrument, my prediction is that setting it up is going to be even more crappy than a Vorson.
At least a Vorson's truss rod
does something.
I wonder of that bridge is better than the Vorson's. One of the biggest problems I had with my Vorson is that the bridge springs rattled like crazy when I have the bridge action screwed down to an acceptable level. To eliminate the bridge rattle, I had to set the action up high. The rattle didn't really affect the tone through the amp, but it sure as hell was annoying!
Edit: Are those pickups humbuckers? They have (cleverly) used a soap-bar style pickup, but there are two rows of magnets on each, which probably makes them humbuckers.
