What is this?

I'd like to see it too with a blank raster.

I don't think the alignment with the guns is nearly as critical as the alignment with the face plate, each hole is supposed to be precisely aligned with each color dot, even a small shift or rotation of the mask could screw it up badly.

Is the mask held in by anything but tension on the glass, maybe some slots it fits into?

There are 3 spring loaded tabs with holes in the end, Im assuming the holes 'lock in' to molded glass nipples to hold it in place.

I will try and take some pictures when I get home.

Thank you! I have been looking for pictures of the spring assembly...IIRC, the holes in the spring clips may actually locate to metal (kovar?) tapered posts that are fused to the inside surface of the faceplate panel...not sure, however.
