Hmm, maybe then it's intended to land in gerwalk and stay perched like that by design. It's like that in the VFX-2 flightline wallscroll as well. Gerwalk mode on the flightline. Actually not a bad idea really. No runway necessary for the Konig. Take off in gerwalk transform, and fly.
That's a lot of weight to put on a landing gear, and gears for a craft as big as that would be HUGE, and would interfere with it's transformation. The gear has to fit somewhere, and there's no space for it on the monster in the legs or on the fuselage. Look at the size of the gears on a B-1 or B-2 bomber, or on a cargo plane like the C-17. They wouldn't fit on the VB-6.
So there we go, it does look like the VB-6 was designed without a landing gear on purpose by the Head. So I would venture to say that what's supporting the shuttle mode on display might be the basic stand it could come with.
