How do you date Hemingray insulators?
The first number (MM) is the mold number, and the second number (YY) is the year (plus 1900) when the mold was made. Thus, “23-42” is mold 23, which was made in 1942. In some transition cases, the number 9 was used to represent 1939 and 0 to represent 1940. There are often dots present after the year code.
