Hi ICON, picked up these two today at a small flea market here in Western Kentucky. Both share a 1947 year of production and both appear to be unused. Please note what appears to be amber streak in both. If the insulators were not used and the streaks are not amber what could it be? I'm going to soak them in wood bleach just to see if the (streak- stain ? ) will come off. Any comments welcome, and as always thanks. Thanks to Steven Bahre for following info: Insulators are CD 113 (ein 090) with a book value of 15 to 20 dollars each.
