I fixed the color issues there were two. The one that killed the color was a lead breaking loose from the color level pot. This set's leads tend to break of their terminals easily (especially the ones going to the tuner sub chassis). The second issue, which has been there since I knocked off the color osc coil during a previous post restoration repair, is that the color lock occasionally gets disturbed. The effort I put in to getting it right after discovering the slug was stuck almost deserves it's own thread (meaning I don't have time to go into it now).
I had little time after fixing the color lock issue, but I managed to do a quick and dirty static convergence, and readjust the horizontal stage, but totally for got to check the purity and rotate the yoke to a give a more perpendicular raster. Hopefully it is good enough that I won't be tempted to mess with it again for awhile.
Well as I was writing this I powered it up for a purity check and lost color synch again (this time it is clear I need to carefully redo the color osc alignment).
This is a picture of what it did when it worked right last night.
