This device is a high-speed reception relay, a charming and fine item made by Siemens in Germany circa 1930. The relay is quite well preserved and keeps all its original component parts and pieces in excellent condition. The delicate electrical circuits and screws that make up the mechanism preserve the old-time wires and connections, creating a lovely and fascinating instrument for any collector. The relay is circular in shape and comes inside a black-bakelite casing. The casing is also in good condition and bears the SIEMENS brand name engraved in the cover. Inside the cover there is a circular paper label with several diagrams showing the relays connections with German instructions. Curious and delicate, this high-speed reception relay by Siemens is an amazing example of the German technology of the early 20th century.
