Residing in a Virginia antique store, Carol and I saw this wood-covered insulator. The insulator inside the wooden case was well made with a channel running from the base at one side, over the top of the dome, and down the opposite side to the base. Its center was drilled to accept a 1" American threaded pin. Part of the sheath of one of the insulators was rotted away revealing the internal wooden insulator.

The outer sheath encompassed the channeled, threaded insulator all the way to its threaded pinhole, so that it was hard to determine how the internal insulator could have become encased. There were two holes drilled in the base of the outer sheath so that the wire running over the dome of the wooden insulator could exit on either side of the pinhole. Bits of stranded wire used in its application could be seen as well as the wooden pin broken off in the pinhole. One of the two insulators has no pin, so the standard threading could be confirmed. The two insulators were dredged from a river in Virginia, and "were part of the local history and NFS." N.R. "Woody" Woodward agreed with our feelings that it was some sort of "dryspot", but we wondered if anyone has run across a similar item on their travels.
