1930-1949 (the "NDC" years)
In 1930 Gillette stopped using serial numbers on razors. So razors made from 1930-49 can be difficult to date precisely. However, blades made in those years were stamped with a date code: A for 1930, B for 1931, etc., plus 1-4 for the year quarter. So "A-1" means January-March 1930. In 1950 this system was expanded to include razors, too (see below). If a vintage razor is found with its original blades, the blade codes can be used to establish a rough date for the razor. This is not 100% accurate, since the blades may not be original or may have been made before or after the razor.
