Let me first say that I know nothing about vintage microphones other than the fact that this is a rare and highly sought after one.   Found at an estate last weekend seems to be in beautiful condition.  I believe this is the 77C1  model from a couple others I have seen   I do not know how to take it apart nor am I going to . it is heavy and weighs about 2 pounds.  It does have a cord that goes with it which I'm assuming plugs into something.  Great art deco look and no dents.  You will be buying this as is so if you have any questions or need more pictures just let me know. This  is really a cool looking piece!
