I'm under the microscope now. I can stand to be corrected from the dimunition of time. The 6 to 3 does seem to be logical as they improved as does the 14 to 21 pin base.

Perhaps we should start another thread just for these efforts. I would like to know how the mechanics of these seemingly eccentric bolts worked. These are not just locking bolts but perform a function...but what?

I am not surprised that RCA had to develop a shadow mask that was moveable for the developmental stage until mfg could catch up with precision.

It would take an artist to move these bolts to allignment under the light box used to align the shadow mask as seen in the documentation. You would think that any one bolt could distort the shadow mask not to mention 5 more.
