This model, produced during the 1950s and 1960s, was only marketed in the US. In 1954, Duncan acquired all of the assets of the US Cheerio operation, and continued selling the old stock and even producing new versions of this yo-yo, but they did not actively promote the line and it was dropped in 1963.
