It may be just evaporated metal from the 3 heaters... IIRC the getters are in the neck, closer to the screen.
Found a pix... there are 6 stirrup getters arranged in a circle toward the screen from the convergence pole pieces. There are no getters near the base.
Sorry about the poor contrast.
Update: found an article with a better pix of the gun assembly.
