One of the primary models in the Hi-Ker line. The Professional Top was made with the same blanks as the older Cheerios. Most original Cheerios are slightly oversized, like this yo-yo, at 2 3/8" Diameter. Some later versions may have been made by Duncan, after buying Cheerio, as they are the same shape and size as the Duncan models of that time.
This Hi-Ker Professional is smaller than the earlier ones, and is the same shape as the Duncan models of that time. Was this one made after Duncan bought Cheerio and Hi-Ker?
