I was up around Ward, Colorado and picked up this imbedded insulator with attached rigging....# 5 pulley made by Samuel Ginns. Inc. out of Cambridge, Mass.....This section of the tree also has a wire wrapped around the trunk that strangulated its circulation.
Any ideas regarding how this was used ??? Answer - Evidently, the pulley was used for both moving laundry lines and by lineman who often used nearby trees to pull utility poles wire. The insulator and heavy gage wire on the pulley suggests this one was used by a lineman,
