    CHASSIS NUMBERS:

    Every receiver that leaves the Kriesler factory is given two chassis numbers.

    The "Production" chassis number is stamped on a card. The card is riveted to the main chassis in such a location that the number is able to be read without removing the chassis from the cabinet. The "Production" chassis number is the number that should be quoted, together with the model number, when making enquiries.

    The second chassis number (Prefix "0") is stamped into the metal chassis to provide a permanent record.

    Both the abovementioned chassis numbers are recorded at the factory.
