It appears Motorola was no longer installing the 23EGP22 at this late date of tube TV production. Maybe Motorola ditched the 23EGP with the introduction of the TS915 series chassis in '67.
Any thoughts?

The set you have is a monochrome(black and white) set. The sets we are discussing are color.
CRTs that end in 'P22' are color, ones that end in 'P4' are monochrome. Monochrome rectangular tubes were first produced decades before color rectangular CRTs.
