Grundig GBM 125 Ribbon Microphone
These funny little microphones are badged by Grundig but contain identical motors and transformers to the Beyer M260. The bodies are plastic, a little like the Sennheiser MD421, and the grills are metal.
This one comes with original box and detachable desk stand. It is in good working order, serviced with original ribbon and new cable, wired to XLR. The output impedance is 200 ohms.
The one shown is sold but I have one more in stock.
