IDENTIFICATION BY SERIAL NUMBER

(non-wooden machines)

    The serial number on aluminum tub models is stamped on the side of the polished crown of the tub. On porcelain tub models, prior to December, 1949, the serial number was on a plate attached on the log under the power unit, or a plate attached to the lower edge of the skirt. Since, December, 1949, the serial number on Model J & N washers is stamped in the skirt directly slow the rubber tub bond, and centered with the potent transfer.
