Glad you found it. I would have commented that while geometry adjustments were always a song and dance number on any vacuum tube TV, certain TVs of the era were far less finicky. Zeniths were among those that were fairly easy to setup, and under no circumstances should any of the controls in a Zenith be at their limit.
The only quirky thing with Zenith was the audio. I don't know the reason (patent avoidance?), but Zeniths often would buzz in the audio, and indeed had a "buzz" control (potentiometer) on the back apron. Other than that, any Zenith should have excellent geometry and excellent vert and horiz lock.
