So I have an American electric horn 205b from 1925 or early 1926 with base. The base is very old as unit and has one small hole for mounting. Base has matching nickel spacer nut for mount to unit. Appears too well made for homebrew as base plate also has old felt bottom. Radiomuseum dates this to 1925 also showing regular horn unit for this in ad dated Jan 1926.
Has anyone ever seen this in a 1925 radio cabinet or 1926? Probably used a smaller horn. Winding test open. Will take apart and polish. With any luck a broken connection. Missing hardware for connections. An interesting piece .now all I have to do is find a mini horn if unit made functional..
