Here is a very nice Shure model 315 ribbon microphone with satin chrome finish. The finish shows some wear appropriate to its age. Please look at the photos as they are part of the description. It is an all-metal mic with three impedance settings. Impedance can be selected at Low, Medium or High to match the requirements of the audio equipment being used. For more information about this mic, see the image of the Shure advertisement above. The mic worked when tested on a pre-amp / voice processor. Because the mic is 60 to 70 years old it is being sold as-is with no returns accepted. So please ask any questions you may have prior to purchasing. Thanks for looking and please take a look at my other items for sale on EBay.
