Looking toward the centre of this Maine village. The six-pin pole line shown here was typical of New England Telephone & Telegraph Company's crossarm construction before around 1910 when 4 to 6 wires were needed. As new subscribers came along ten-pin arms typically were the rule after 1910 or so. These sometimes were mounted beneath the six-pinners and had a single center bolt method of attaching the crossarm to the pole. Earlier lines (typically 6-pin arms like this one) utilized two diagonally-mounted lag screws to mount into the pole, using crossarm braces mounted *over* the crossarm (which always seemed to be a NET&T or Ma Bell way of installing braces). 6 over 10 pin "then-updated" lines were commonplace (as seen within a lot of my other vintage pictures from here in New England) and this earlier construction as described above was in place until their older poles were gradually replaced.
