Zenith B1717J portable, anyone?

[John in MA]

I've never really gotten into vintage TVs, but I picked a couple up the other day that look to be easy projects. One is a Zenith B1717J portable. About 16" tube, B&W, and fairly stylish with a large tuning knob jutting out of control cluster on the front top edge. I'd guess late '50s.

Anybody have information on this series of sets? Age, schematics, model-specific issues, etc. It's in excellent shape, and has sound and high voltage. Seems to just need the vertical scan repaired and a general age restoration.
