Yes, the Admiral has a different shape, a slightly stretched double D :



I don’t have a nickname for that shape, and usually just mention that various manufacturers used different mask shapes for round tubes, from completely round to a fairly strict 3 x 4 to best satisfy their customer base, as they perceived it.

In my tv room, I have samples of round and rectangular magnetic deflection crts as well as electrostatic and flat “watchman” crts to pass around and discuss, if desired.
