Manufacturing location
Tim, the North Canton, OH address on the Hoover tag is because that is where the main offices of Hoover were located. For example, a Sears Kenmore says "Sears, Roebuck and Co., Chicago, IL" as that's their main office location, while the machines were made by Whirlpool in Clyde or Marion, OH or elsewhere depending on the item. But Whirlpool is not mentioned on the tag because they make them under contract to Sears. Therefore, Blackstone wouldn't be mentioned on the Hoover tag for the same reason.
