I think he's right though. In documentation I've read through, there
were green and amber models offered for the successive generations but
I don't recall having read that the VT100 or earlier models had
anything other than the white phosphor.
I think that is correct.
I've never seen, nor heard of anything but white phosphor VT100s.
*However*, there were clones made by other companies (unfortunately I
don't remember any names here), which looked pretty much exactly like
the VT100, and which did come with green phosphor.

The VT102
User Guide on vt100.net shows that you could get a green
antiglare filter: <http://www.vt100.net/docs/vt102-ug/chapter10.html>
It is
also reasonable to think that DEC did a run of VT100oids with green tub

phosphor VT100s.
Many years ago I saw a VT100 with what was cal;ed a 'retrographics board'
fitted. This was a third-party add-on that connected to various
connectors on the normal VT100 logic board and which gave (for the time)
high resolution graphics. (No, I don't mean a VT105 board, this thing
allowed to you to set or clear each pixel).
Anyway, I seem to rememeb this unit had a green phosphor CRT in it. It
was almost caetainly not DEC-original, it was probably changed when the
retrographics boar dwas fitted.
As I've said before, these monochrome CRTs are pretty generic. And I
rember seeing adverts in Byte for replacement green or amber phospor CRTs
for various machines. It's very possible that some VT100s were modified.

It was partly a DEC product :-). The chassis,case, keyboard PSU, bideo
board and logic board were all stock DEC parts. There was a paddleboard
(non-DEC) in that bridging edge connector that intercepts the lines to
the RS232 conenctor. And another board full of chips (including IIRC a
Z80) to do the graphics.
I assumed from the name that this board could be retro-fitted into a
stock VT100.

Well, by "wasn't a DEC product" I was talking about the board,
which was sold to fit into existing VT100s. The one I had wasn't
installed in a terminal when I got it.

Yes, my googling tells me so :)

Was this part of the fairlight synths, maybe a fairlight product?

Ah, I was a bit fast to reply. It was made by "Digital Engineering, Inc"
here are some pics of the chassi:
