The RCA model 77 series of microphones were so popular that their distinctive form was widely copied, particularly in Japan. They produced a vast number of microphones which echoed the capsule-like shape of the 77, and the yoke-style mounting arrangement at a fraction of the cost of a real 77. This microphone is labelled Argonne AR57, with a red logo. It's a crystal microphone, well made, very attractive, and popular among collectors. The metal parts are chrome plated, and the black areas are Bakelite. The badge is a chrome plated casting, with enameled background areas, giving a cloisonn̩ effect. The perforated shell is lined with white silk fabric. The same basic microphone (with minor variations) was sold under dozens of names and model numbers, including Argonne (sold by Lafayette Radio for $4.95 in 1962), Calrad, Crown and many others. The body is about 6 inches long, and it is about 2 1/2 inches in diameter, about 2/3 the size of the RCA 77.
*crystal mics have a thin sound and low output compared to dynamic or condenser mics, do not expect this to sound like a modern microphone
