Are this things made from unobtainium or what?
 I can't seem to find a supplier for these, other than in India. I have also struck out trying to find any drawings of them to make a set. Surely they can't be that rare???

I can't see their utility.

Didn't know there was such a thing other than for welding.

OK, I can see the applications but there seems to be more precision (cost) involved in a pretty set like that.

Nothing more than a block holding a pair of ball bearings really. They don't need to be precision high-speed bearings.
I have a miniature set that is part of a fixture for straightening aluminum arrow shafts. Beats buying new shafts every time one gets tweaked from taking a hard hit. I have even used it to balance the rotor blade assemblies on my RC helicopter back in the day. I'm just looking to step up in size so that I can handle larger shafts / projects. Folks like Keith Fenner (Turn Wright Machine Works) rely on them for the bulk of his business rebuilding marine shafting. By the way, he has some great machining videos on YouTube, well worth watching if you haven't seen them.
