Henry F. Bray, 71, a retired international sales manager in Washington for the AM International company, manufacturers of duplicating equipment, died Sunday at his home in Tucson, Ariz. He had a heart ailment.

Mr. Bray, who was born in Adairsville, Ga., lived in Washington and then in Silver Spring from 1941 until 1962, when he retired and moved to Tucson. His work with AM International involved travel to Europe, Latin America, the Middle East and elsewhere. He also had two patents with the firm for duplicating equipment.

He joined the company in Albany, N.Y., in 1930. At that time, it was called the Addressograph-Multigraph Corp. He was a branch manager in several cities before being transferred to Washington.

Mr. Bray was a licensed "ham" radio operator. He built his own radio equipment, held an advanced class anateur radio operator's license and was a member of the Anerican Radio Relay League. His hobby included providing "patches" for radio-telephone calls from overseas, including some from servicemen in Vietnam during the war there. He did this as a volunteer.

Mr. Bray's survivors include his wife, Mary Lee, of Tucson; three daughters, Jean Ellsworth of Visalia, Calif.; Betty McAtee of Largo, Md., and Nancy Bray of Anaheim, Calif., and three grandchildren.
