Zenith out of cabinet

[ShartZenith]

Got the chassis out of the cabinet today. Broke the cap part of the brightness knob off its base but think it can be epoxyed back together. Bigger problem is the grey plastic ring that encircles the picture tube. It's broken at about 11:00 into many pieces and at the base, 600PM where the plastic mounts onto the chassis with two sheet metal screws. It would be a chore to glue all the pieces back together and not sure it would ultimately hold once reinstalled around the tube. Photos attached. Anyone have a good used one they want to sell?
