I have a 10x22 Grizzly and it looks very similar to mine. As Bmachin said I am sure it is made in China/Korea and marketed under various names.
That tail stock and carriage is identical to mine as is the gear exchange. I have had some issues with the tail stock....when I thread with dies on metal it puts pressure on it and sort of locks it up and needs to be disassembled and reassembled as it id "jammed" unless you lock it down with the set screw and lock down. With pen stuff it has performed flawlessly. It really looks like mine, some of the controls are rearranged a little, but even the font is the same.
Mine has a DRO which is basically worthless as it is not accurate (even considering backlash) but I would do it again for sure.
With you being a Machinist maybe you can make suggestions on the tail stock problem.
Oh, I just thought of one complaint, the Tailstock travel is only 2.5". I have a Laguana 18/36 which is 4", but drilling blanks on a metal lathe is far more accurate. Are you going to get the stand? That looks like a nice set up! Keep us informed!!
