No, I did not figure out the manufacturer, and I saw the same CS logo on other college rings that look just like this one. It appears that they made these rings for quite a few different colleges, just changing the emblem for each one. It does appear that the wide band style fell out of favor after the 50s in favor of the class rings we know now. The former owner of the house went to University of Georgia, but this was not her ring. So my best guess on the age is still 1930s -1950s, probably 50s. Some friend from college must have dropped it here on a visit.
