These microphones work flawlessly. I can provide a sound sample, if you send me a message. These are from 20th Century Fox, and are as a result engraved T.F.C. at the bottom. These come with Neumann holders and Beyerdynamic clips. All of the items are packaged in a beautiful wooden case. The case has a slight smell, as smoking was permitted on the sets and these were in storage at Fox for a while. These are a cool collectors piece from 20th Century Fox, as well as fully functional, high quality microphones. I will ship worldwide, but buyer pays shipping and and customs charges. Please see pictures for best description possible. Feel free to make an offer. Thanks for looking!
