IIRC, that's the first year for that CRT and the big heavy front glass panel.
I keep forgetting those sets are 50+ years old and subject to large component failures.
Remove the CRT and inspect the yoke windings, as suggested. Take resistance readings of the vertical windings. They should both be alike. Around 15 to 25 ohms. If there's resisters across the windings, disregard them. If the winding is open, you'll just read the resisters.
