This city is a few miles north of Boston and had a lot of open-wire Gamewell fire alarm circuits all over the place. It is possible the lower crossarm circuits seen here carried those lines. A fairly good number of 7-Up Green Hemingray-19s with round drip points were used with other interesting glass along the old fire alarm openwire that this city once had through the late 1980s. These "glower" Hemingrays with their slightly yellowish highlights within their glass really stood out like crazy upon the crossarms they were mounted upon.
