If it's an Admiral from that era, it probably has a 17BP4, 16TP4 or similar.
That's where the chassis number come into play. The CRT number should be on the tube location diagram.

I don't have a tube location chart. It very well might be a 16tp4. I tested it as a 16ap4. But. You may be right. I'm gonna test all the tubes in a minute.

With rare exception most CRT's from that period used the same basing and tester settings, so your results testing as a 16ap4 should be fine.
