so is the face of that tube a greyish or a little greenish in color. More like the color of the early 15GP's or more the color of the 21axp's? I wonder if the 1b3's meant the tube was designed to have lower beam current. Too bad there ain't a Sam's you could order for that chassis.

It looks greenish to me, kinda like the 21AXP22 in my CTC-2B. I have it parked right next to the CTC-4 at the moment, and it's very obvious the difference when viewed right on. The screen on the 2B almost glitters, while the one in the 4 just looks like plain paper.
