    This is actually the first one of two now in my collections, the other just having arrived the other day from another collector of traffic control equipment. :-) :-) :-) SEE ALSO, for further info:

    This is a 7lb chunk of thick cast iron measuring roughly 6" x 9" x 3/4". It was once the end cover for an electrical junction box with connections to a pressure pad sort of apparatus which was actually *set into the pavement* of a street or roadway as a "traffic detector". (that worked with other related equipment, before modern equivalent technologies developed for the purpose) Bolt holes are recessed at each corner and the underside has a part# P-255 cast in, the topside has the ELECTRO-MATIC name logo as its most prominent center feature, with "AUTOMATIC SIGNAL DIV." as the top line.

    ALL THE ABOVE is common to both covers, the differences determine that this one is newer with the further wording. This one is next labeled "EASTERN INDUSTRIES INC." as the second line, with "NORWALK, CONN" as the only line below. In earlier production, the molds were different and the wording reflected the parent company's structure at the time. This one nearly looks less worn down than the other as well, but this is also more likely an original casting variance.
