Is this a bad CRT? 10BP4

[CJVx]

Hello, after a re-cap on my RCA T-100 chassis, it has came on showing a strange picture that looks like a stone engraving for lack of a better description. Also experiencing significant blooming, what I think are overscan lines and the behavior of the focus control will only show the sharpest focus when the wiper and element are shunted (fully turned clockwise). Unfortunately I do not have a CRT tester at this time, but still gaining experience on vintage TVs, I would like to hear the thoughts of some more experienced people on here. Thanks!

PS, when the video and AGC tubes are removed, just leaving a raster on the screen, I still see similar overscan lines and blooming/ loosing focus when the brightness is increased, indicating there is something else going wrong further down the line.
