Gillette Date Codes

In 1930 Gillette started marking their blades with date codes. A 1/2/3/4 (Letter=year, number= quarter of year). In 1950, they started marking razors with the date codes. The following chart is a list of my dated Gillette razors. Following that is a chart explaining the coding system Gillette used from the beginning.
