Trying to identify this keyboard as a challenge

[akkk44]

I know the image looks like sh*t and may hurt everyone's eyes, my apologies.
So far I have noticed some features：
Narrow F keys;
Sharp MZ-700 like arrow keys;
4 2U-keys one the numpad.

I am trying to identify this keyboard as a challenge, anyone have a clue?

The stacked arrow cluster and half height top row was used by Siemens for a while. My first guess would be it's a board for a clone of one of their systems.

I'm guessing it could be an early PC XT or AT clone, but after the Model M had been introduced.
The function key row having ten keys, the vertical Enter/Return key and the wide keys on top of the numpad point in that direction.

I believe I own this board, or at least a version of it

Mine is a Futuba MA inverse mount, caps are doubleshots.

The below picture is from the listing when I bought it.



Hope that helps!

Wow, you inspired me a flashback... Mine may be the little sister. Let me know if you aim at bringing the family back together and I'll let it go. [WTS]
