Regarding your other question (pinout), I will let those that are more experienced comment about that.

Correct on the ion trap. On the pinout, the only differences are whether the replacement tube is electrostatic focus or magnetic. Again, you can swap by making a couple changes. But most all TVs made after appx 1953 had static focus.
