I recently came across these two M-4395 OB cross tops with connecting bracket. This was used to help stop lightning flashovers on this early NY line from Niagara. I used a porcelain flower pot filled with cement to hold the thing up (which my daughter is standing next to). The othr two "kitsulators" are a Fred Locke 3721 and New Lexington 4325A, both from the early Borel Powr Line in California (early 1900's). The wall tube on the ground is rare, and is an early Thomas style from the Childs Power House (1908) in Arizona. It is mint! All the best, Reed Thorne
