Milton is a Boston suburb, bordering with the city on its southeast corner. The Edison Electric Illuminating Company of Boston was the utility in this community when this photo was taken. In 1938 the E.E.I. Co. of Boston became Boston Edison.

The latter used glass distribution insulators well through the years, very often carrying them over to new poles during changeovers (the present utility, Eversource often still does this). Most of the glass are common styles, such as CD 164s, 165.1s and 167s and some of the manufacturers were Star, Brookfield, Hemingray (after the early 1920s), Gayner, Whitall Tatum, Armstrong and Lynchburg (these did not have drip points). During extensive line rebuilding during the 1910s only deep groove, double petticoat insulators were reused (these generally were CD 164s). All other styles encountered were taken out of service. These particularly were CD 134s and 162s that were on the old lines. I am sure there were some rare styles and designs on the original circuits before standardization.

On this utility pole (which does not look very old when this photo was taken) the insulators mostly appear to be CD 164s. A fire alarm circuit is on the top and lowermost crossarms.
