This is the bottom of this pole. See link for the top. [id=196995083]. Do you think this is a pole date code or just a pole ID? Would like to here from any WA, state collectors that might know. Trying also to get the insulator manufacturer's and CD's this pole might have had on it when it was installed. Now it has Hemi 42's and 45's a few BF 152's and one porcelain. Would like to add some more color, and other styles used originally for this 25 pin set up. What do you think?
