Help to identify communication device
I come to this forum looking for answers. I have come across an object that I believe to be military and pre 1960. I’ve asked several military museums and experts but have yet to get a positive ID on what this actually is. It is cast aluminum and on it are the words "tone" and "voice". I think it’s some type of radio casing. But in all my research I have yet to come across anything similar. I’d love any help or theories on what exactly I have here. It was originally found in a junk yard in the 1980’s in Souther California. That’s about all I know. Below are pictures. Thanks guys!!!all%20view.jpgIMG_2189%20%28Large%29.JPGIMG_2190%20%28Small%29.JPGIMG_2191%20%28Small%29.JPGWHE1%20-%20110404.JPGall%20view.jpgIMG_2189%20%28Large%29.JPGIMG_2190%20%28Small%29.JPGIMG_2191%20%28Small%29.JPGWHE1%20-%20110404.JPG
