Got the cabinet cleaned, it turned out really nice. It had been sitting in a basement so it smelled pretty musty. I used Murphy oil soap on the whole thing inside and out, then Old English scratch cover, then Johnson's paste wax and the cabinet came out great! After that I put it outside on a sunny windy afternoon and now you would never guess it had ever been in a basement.
The brass feet were pretty nasty looking, so I tried the ketchup trick. Coated them with ketchup and let sit for an hour, then rinsed off. It actually worked great - I repeated it twice, then used Noxon 7 metal polish and they came out awesome.
The chassis had a film of junk on it after vacuuming it out, so I used dish soap & water and wiped everything down and it turned out well.
Last thing I did was change the vertical cap and see if that cured the poor height/linearity. It was one section of the can mounted to the top of the chassis and tested open. It's a 100uF @ 50v, I found one on an old circuit board that I had, it tested good so I put it in. Now I have full vertical, but there are two images, one on the top half and one on the bottom. The vertical hold locks in right in the center, and the picture has a strobe effect. I'm going to get a new cap and put it in before I do anything else and see if that gets rid of the weirdness.
