UNEXPLAINED STAMPINGS and FOREIGN LABELS
A stamped marking that appears on a number of Stanley axes includes the commonly recognized notched rectangle with the name STANLEY on the inside. To either side of the notched rectangle the stamping included the capital letter "M". To date this mark raises the question as to what the letters "M" refer to before and after the notch. At this point, suggestions are that the letters may mean Mexican Made of perhaps Mann Made.
In 1966 the Mann Edge Tool Co. purchased the Collins Co. along with all the manufacturing equipment located in Collinsville, Conn. At that same time STANLEY TOOLS, a division of the STANLEY TOOL WORKS, purchased the three Collins manufacturing facilities located in Central and South America. It is believed that part of the overall agreement was that the Mann E. T. Co. would not market axes bearing the name COLLINS CO. south of the US / Mexican border.
That suggests the possibility that the Mann Edge Tool Co. entered into an agreement where they would manufacture long-handled axes for Stanley and that the axes would bear the name Stanley along with the two capitol "M" letters. Perhaps they stood for MANN MADE. The answers to these questions are currently being explored.
Observations and catalog references indicate that most "M STANLEY M" axes that bore the No. 53-313 handle mark were made in the Michigan pattern, as they appeared and were so noted in Stanley catalogs. Recently another example has been observed that also includes the "M STANLEY M" stamping and the No. 53-313 3 1/2 LB on the handle but it is a Cedar Pattern axe not a Michigan pattern axe. Such a pattern has not been seen or reported as appearing in any Stanley catalogs.
Adding to the confusion is the observance of a Stanley label on a machete along with the wording "Made By Stanley Tools in Columbia, S. A." This observance adds validity to the fact that Stanley was manufacturing in facilities in South America. At this point, there is no evidence to show that Stanley manufactured axes or other edge tools in Central America but a recent observation of a label on a machete includes a label indication that the machete was made by Stanley in Columbia, S. A. The time frame for the machete is believed to be the last quarter of the twentieth century.
