There were no razor serial numbers from 1931 until 1950.
Razor Date Codes began in 1950 and used the same system blades had used since 1930, a code that identified the year and calendar quarter of manufacture.
Gillette is one manufacturer for whom we have information on serial numbers and later date of manufacture codes that we can link to time.
Razor Serial Numbers were impressed on all Gillette razors from 1904 until 1921, and on deluxe models from 1921 until 1931 (except for a period in 1927-28).
