Thought I had seen it all.  Looks from the side and rear views like 
a heavily remarketed VT52.  With a MR-78 unit, whatever that is.
There also looks to be a floppy access plug in back there.
Missing the RX01?
I think it's saying WT := Word Terminal.  First one seen for me.

Yes, this checks out here:
