I don't know about "Raleigh USA" Huffys, but they imported English Raleigh-built 3-speed Sports models (sold as "Huffy Sportsman") and also imported Carltons under the Huffy name briefly. When I first encountered American Huffys on moving to Dayton in 1959, I, a mere fourth-grader, was disdainful of their inferior construction.
