1. Plastic cover - bell shaped, blue front and white plastic back. The front and back form an envelope for the calculator. The commemorative gold shield printed on the blue plastic reads "TEAL / 21 / YEARS / 1940-1961".
2. Discs: Two discs are joined through the centre. One disc is serrated to facilitate turning. One face has "The Auto-Date for 28 years". Gold background with black lettering. Inset windows provide basis of calculation by revolving the discs against each other. The reverse side of the discs gives exchange rates for various countries for measurements, both Imperial and Metric. Also weights for liquids and solids and their conversion. Disc diameter = 50 mm.
3. Key Chain: A key chain loop attachment 60 mm long is fixed to a disc and passes through the plastic cover.
