A rare find! This is a vintage Inada IDM-3 dynamic microphone, manufactured in Japan during the 1960s and the 1st one I have ever come across. It features a striking Art Deco styled design heavily inspired by the iconic American Astatic 77 Dynamic microphone. This specific variant stands out due to its slotted, rectangular front grille design. It's a high impedance mic, commonly marketed towards for public address, amateur radio, or general recording.

      During the 1960s, Japanese manufacturers produced this same basic microphone body under a variety of badges for different importers, including Calrad, Midland, Monarch, and Teisco). The Inada brand badge on this one is considered one of the rarer regional variants of this classic design. It includes an integrated on/off slide switch on the base collar and sits on a adjustable tilt joint for desk/floor stand mounting.

      Today, these vintage high-Z dynamic mics are highly sought after by harmonica players ("blues harp") and experimental musicians for their distinctive, lo-fi, mid-range grit with vintage warmth, and this one strongly fits that profile. (Check out the voice sample included on the listing video.) A 2' cable is hardwired with male XLR plug, and includes the basic display desk stand.
