Bang & Olufsen Beomic BM3 with box, stand and cable.

Designed by Erik Rørbæk Madsen in 1962

A fantastic looking microphone, tested and working.

Info from Beoworld: 

Features: No resonance peaks. Extremely smooth response. Bi-Directional – no side pickup. No frequency discrimination, front to back. High efficiency Nu-Metal transformer placed in microphone housing. Switch for muting and voice/music conditions.
