Thiele M5

Translated from MikroSammler website (originally in German)

"Werner Thiele ran a small microphone company in Leipzig, from after 1945 until approximately 1960. Initially, he manufactured bottle microphones for the Schneider company in Merseburg. In 1955, Thiele released his first model under the Thiele name – the M1. This was a bottle microphone without the attached torpedo-shaped capsule – the capsule was built directly into the microphone. In 1957, the Thiele M4 was introduced. These were available in various colours. Simultaneously, he developed the Thiele M5 which was the first model with a separate power supply. The M5 was significantly smaller but visually similar to the M4. Around 1960, Werner Thiele left East Germany, and his employees continued the business. To prevent nationalization, they founded a cooperative (PGH Elektro-Medizin & Vakuum-Technik) and continued manufacturing and distributing the microphones under this label."
