As far as a I know, NEVER done, because it would require separating the face assembly from the bell. The phosphor dot pattern in a color tube is unique to the particular shadow mask used in that tube. The process requires inserting and removing the shadow mask three times. There were attempts at making interchangeable masks and faceplates, but even then it would be necessary to disassemble the face assembly parts from the bell in order to re-pattern the face.
