Horrible photos, cannot figure out what the connector is. I'm going to guess it's a Centronics 24 pin but am not sure whether or not Wang used them or not. I might try to convert it as it has a solenoid

.
Will put in more details/pictures once I'm home

Your photo's are fine. I was looking foreward to seeing this. Thanks for sharing. Are the function row keycaps and the others missing? A solenoid is always nice.

I was in the middle of taking caps off, and decided to take pictures... All caps were included.

Right cool, that's what I thought.
The base of the switch reads "4T2B"? And that top row "A26B"?
We have these in our wiki:
T4A2B - Wang 271-1126 (Meaning of T is unknown)
4A2K - Wang 271-1126
4B3K - Wang 271-1126

I also do not know how to disassemble it... I would like to take the plate off so I can clean the switches with corrosionx, but I have no clue.
Switches found on my keyboard 271-1247:
4A2B, 4B3A, 4T2B
Edit: found 4B2K on delete key

I finally disassembled the keyboard; now all I have to do is order a bunch of corrosionx

OK thanks for the switch numbers. It looks like the plate may be locked to the PCB by those three metal hinges below the function row.

Did you buy it on eBay? If so... Good job. I made an offer and hoped that, if I didn't get it, someone from the forums would document it.
