Copal Digital Clocks — U.S. sales brochure

Ten scanned panels of an English-language Copal clock sales brochure, arranged by the uploader’s numbered scan names. The back panel identifies Copal Corporation of America in Woodside, New York. This is U.S.-market literature and does not establish the voltage or specifications of a Japanese domestic-market version. The printing code reads “SE76121E”. It may relate to a 1976 printing, but that interpretation is not independently verified; the exact publication date remains unconfirmed. The separate photograph of a boxed clock in the source album is not a brochure panel and is not included among these scans.
