This very popular cable style insulator is nicknamed the "Mickey Mouse" by collectors for its trademark ears, and was produced in two versions: a regular saddle groove and a wide saddle groove (later denoted as №60-A) to accommodate larger cables. The design was patented on June 17, 1890, and earliest specimens produced by Hemingray simply bear the May 2, 1893 and June 17, 1890 patent dates. These come in a range of clears, blues and greens, with the electric blue color being the most desirable (not to be confused with the much more common Hemingray Blue!)
