Dating a Millers Falls tool was easy for a brief time

 Primarily in the 1950’s and 1960’s, Millers Falls stamped the inside bottom of the box with the date the tool was packaged. The date format is in a numeric month and two digit year. This ink stamp also included a three to four digit numeric number. If you look at enough of these stamps, you can see the numbers are each individually stamped. This state-of-the-art approach can lead to mistakes such as reversing the year and changing the order of the three fields. I’ll point out a few that were found. One option on what the three to four numeric code will be entertained.

 Employee Number

The following list is a tabulation of over fifty examples taken from ink stamps found inside of boxes. The employees at Millers Falls had badges with employee numbers. One guess as to what the three or four digit numeric code is would be an employee number. You can see that some of the numbers are used over many years.
