I'm looking at a can containing an exposed roll of Kodacolor-X, (CX 135-20). Probably 1970 or thereabouts. The can body is plain alloy with embossed Kodak signage and the top is yellow. The film cartridge is yellow, including the end caps, with black printing. The film is marked Kodak Limited London.
Not a film can, but I have a booklet entitled Kodachrome, Photography in Color published by the Eastman Kodak Company Rochester NY, cover price 25 cents. Not sure of the publication date, but 12-39 appears on the spec sheets in the back. The booklet covers a wide range of topics.
