This insulator was recently found on the shore in Northeastern USA by a beachcomber and his daughter. I wrote an article in the April DRIP POINTS magazine for anyone who wants more detail. It is amazing how Harloe stold this design from Brooke more than 20 years later. Enjoy the photos. Embossing reads PAT. MAY 26, 1874 over AUG. 25 1874. Both are BROOKE patents.
