Wow...nice find!!!
Terminals in the 1990's were just that to back end big boxes (mainframes), Unisys, IBM, etc and used serial connectivity.
In the 1970's would play Star Trek on a teletype printer terminal in the water closet adjacent to my physics lab (a 6 hour class).
CRT University terminals were in the same building arranged circularly. While it was a University building it was owned by the government at the time.
Played Star Trek there too.

If VT300 means DEC then it would be VT300 series rather than a particular model.
The mount for the screen looks unusual to me but the keyboard looks like a DEC one.
VT330 (etc) monochrome async dumb terminal - some had 2 async ports (and could split screen) other had special proprietary DEC protocol to run 2 sessions down single serial cable.
Any labels on the back of the monitor?

Paul ,
Not that I can see , will examine more closely when I return to the site .
The screen and mount are the coolest thing , it's like a consetina type thing that moves right up , then back down in to that circle thing in the base.
I'm thinking of a use for it , pretty sure it won't work again as it did once apon a time .
So a possible project would be to pair it with a ZX80 / Zx81 with the current CRT .
Or
Gut the CRT and add a Pi Zero or Pi 3 for some sort of project
