This typewriter was made between 1979 and 1983 in the United States. These dates are an estimate:
Smith-Corona began using brown plastic cases in the late 1970s, and ended manual typewriter production in 1983. By 1982, the ribbon cover had been redesigned to resemble the Coronamatic electric typewriter.
