Photo circa 1900. In the c.1880-1915 period (correct me if I am wrong!) a lot of the telegraph lines here in New England were strung on six-pin crossarms as shown here. I believe these were an "upgrade" from short two and four-pin crossarms used in the early threaded glass days (after 1865). I am familiar with the Webster line as shown here and found numerous B&O insulators along it as it continued into CT. I hunted this line which was cut down in the 1950s or 1960s with the late Margaret "Mike" Oveson of Grafton, MA in late 1968. She was one of the pioneers of the Yankee Polecat Insulator Club, founded November 1971. "Mike" was well known for her fine detail and discovered that telegraph lines once ran on *both* sides of *this* track, likely one by the Baltimore & Ohio Telegraph Company and the other by "competing" Western Union. Of interest, I still have a couple uncleaned (as found on the ground 40 years ago) B&O insulators. All discovered were aqua except for a few in light green. From (later found) old photographs taken of this line leading into CT, American Insulator Co. insulators were clearly seen. Fragments have been found as other collectors searched in the 1970s and 1980s; all of common styles.
