Other engineers ⁴ working for Coto-Coil were Granville P Lindley b1891 (Lead Engineer of the Byrd Expedition II) ³ and Lewis Bellem (1BES). Lindley and Bellam were also responsible for bringing Radio Equipment to Pitcairn Island in the South Pacific made famous by the landing place of the mutineers from the HMS Bounty. The island, cut off from the rest of the world since 1790, received a modern short-wave receiver and a 60-watt transmitter in 1938. The equipment was made possible by the generous donation of material and labor of many amateurs and manufacturers under the instigation of the Coto-Coil Company. The companies involved were Aerovox Corporation, American Lava Corp, Amperex Electronic, Bassett Research, Biley Electric Company, Cardwell Manufacturing Company, Coto-Coil Company, Kenyon Transformer Company, Ohmite Manufacutring Company, Par-Metal Products, Parris-Dunn Corporation, Pioneer Genemotor Corporation, RCA Radiotron, E M Sargent Company, Shure Brothers, Triplett, Willard Storage Battery Company.. ⁵
