From what I can tell the badgesticker says Oshima but I have no idea what it went to, who actually made it, or literally anything about it.
Look at the cool plate though, very nice. Spacebar stabs suck, but you can flip the spacebar pretty easily which is funny but not actually comfortable. The caps don't fit well and they all look like they were glued to the stem initially before the glue degraded so much. The caps are pad printed or maybe silk screened, it's inconsistent as hell though even if it is pretty sharp otherwise. The flashing on the caps is also pretty bad, worst I've seen so far.
And onto the actual fuckery:
Why is the cable tied down like this
Why do the tape drives run through the keyboard
Why does this do R1, R3, R3, R3, R3? it isn't even consistent, some of the stepped keys aren't the same profile as the other keys in the row
The PCB is designed to use another switch and it was modified to accept SKCC
Like look at that fuckery.
I've seen another listing for a board like this with SKCC, and another with SMK, and I think the SMK version is the normal one with this being the modified version.
All in all the profile makes it hard to type on, the spacebar stabs suck, and the caps aren't very good. It's an interesting board but I wouldn't recommend getting one unless it is cheap and you just have to collect all the SKCC boards like I do. It sounds nice enough (space bar excluded, lube might help) but that's it.
