Two Western Electric 639A mics. These predate the Altecs but same microphone. The first pictures\' mic the ribbon works- sounds great but the dynamic component does not work. These mics were made to be a ribbon, dynamic, or a blend of both. So at the very least you could have a nice vintage ribbon mic but if you wanted to have the dynamic cell fixed you could have both. Slight cosmetic blemishes but to be expected with a 70+ year old mic. I am including the second mic as well it has more cosmetic damage, the outside ribs need some gluing and the mesh needs to be replaced but it is the same on inside, ribbon works and dynamic cell does not. Could either repair this mic and have a pair of these or use for parts. Let me know if you have any other questions!
