Hi!

Is anyone familiar with the 21AXP22? This one has the registration marks visible through the front screen, at the top and bottom.

I'm curious if this is typical of all 21AXP22 CRTs, or just some (this is serial #K-3620).

Over the years I've found a few RCA developmental & prototype items in this area of Northeastern NJ (including the 16" metal/glass color CRTs which pre-dates the CT-100).

Thanks! Harry
