What you wrote is what I more or less thought. It now boils down to
one question: is there RF on two of the three HV leads? If
so, it TRULY IS a chromatron, not just a larval Trinitron. If there
is no RF on any of the three leads, I would call it a larval Trinitron.
This question could be answered by a schematic or a scope with
its probe merely held a half inch or so from the CRT HV wires.
I believe the owner has a schematic ... it would be wonderful if
he could scan and post it! (the 7010U, not the 7010UA).
