In 1968, C. G. Conn Ltd. was manufacturing more musical instruments and accessories than any other company in the United States. It had prospered since 1915 under the Greenleaf family, but had begun to decline when the demand for school band instruments declined in the 1960s. President Leland Greenleaf sold the company in 1969 to Crowell-Collier MacMillan, apparently to avoid a takeover by another instrument manufacturer. MacMillan shut down most production in Elkhart, relocating to areas across the southern United States and even Mexico, including a brasswind plant in Abilene, Texas. Student (and apparently some professional, see source 1, source 2) brass production was moved to Japan, through an agreement with Yamaha/Nippon Gakki. I personally do not know how long production was kept in Japan, as 1970s student cornets and trumpets say "U. S. A." on the bell. In 1980, Daniel J. Henkin bought Conn and tried to boost the company, but, due to health and foreclosure threats from a credit corporation, sold it to Skäne Gripen, under pressure from Bernhard Muskantor. This ended up in litigation later on, but Skäne Gripen pooled the Conn companies into one called "United Musical Instruments" [UMI], which was purchased by Steinway in 2000, and integrated with Selmer [to form Conn-Selmer] in 2003.
