I agree, this is a dandy performer. I remember those rings well. Didn't seem terribly sturdy.
Mine looked terrific after I finished recapping it , except the picture was slightly tilted off level. Nearly drove me nuts. With the chassis outside the cabinet, I adjusted the yoke to level it, using a spirit level to confirm that the chassis was level on the workbench, and temporarily collapsing the vertical and holding the level against the horizontal line.
It looked perfect on the workbench, but tilted again after I put it back in the case. I even tried tilting it in the opposite direction on the workbench, then reinstalling it. After about three go-rounds, I declared victory and left it with the slight tilt.
Someone suggested that the cabinet might have become magnetized (?).
I have a cosmetically nicer one waiting in the queue. If I get around to restoring it and have the same problem, I'll know that I'm bewitched
