The pictures show a front and back view of this Old Atlantic Steel Castings Company Advertising Employee Badge Pin. This employee badge is not dated but it is believed to be from the 1940s for World War II war production use. The metal badge has a clear (but cloudy) center section over the number. It is marked on the two sides as follows:
THE ATLANTIC STEEL CASTINGS CO. 54
WHITEHEAD & HOAG
The numbered badge measures 2'' wide. It appears to be in fair condition with much wear from use as pictured.
