90 or 110 degree TV

Measure the angle between the start of the CRT neck and the edge of each side of the tube. Usually the angle will be part of the CRT part number too.

Measure the width and the depth. High-school triginometry will figure out the degree.

There is still a yoke on this one. Is depth from dead centre middle of front of screen to the most forward part of the yoke or to middle of yoke? And is it true horizontal width or the diagonal "width" ?

It's from wherever the beam is deflected on that particular tube, the available angles are far enough apart that it shouldn't really matter where you measure from, anywhere on the neck should get you close enough.
