These two came off a single six pin arm line out in the orchards, south of Yakima, Wa. (if I remember correctly) in the spring of 1979. There were lots of this particular mold type in this area, but these two are identical in color and each sports a strong olive steak that doubles over itself right behind the "D" on both. They were not used on the same pole, but were used in close proximity to each other on the line. I noticed the similar characteristics when we got them back to the car and have kept them together ever since.
