Hello and welcome to The House of Chrome.

 You are looking at a desirable older used Amphenol male 2 pin (model # 80-M-385) microphone cable connector / jack from the 1950's - 70's. These vintage model connectors were commonly used on Electro Voice microphones and E.V cables before the modern XLR cables became the standard. Shure made a few 2 pin mics as well including the 430 "Commando" mic. 

 This connector was used on a few specific microphones form Shure, Turner and Electro Voice and it was used with a cable as an extension for a male 2 pin cable.

 As you can see in the pics provided this connector is in very good overall condition with no wear and has all the original pieces. Nothing missing. This male 2 pin connector just needs to be soldered to a cable of choice. The plastic insert with the 2 pin slides out and held in place with the side screw.

 This connector will require soldering and it's a bit tricky so if you have those skills then this will do you justice. If you don't have the experience or ability to solder then I would suggest saving yourself the time and headache by simply buying a complete cable.

 It's reasonably priced and will do anybody justice who needs one.

 Pics # 7 & 8 is to show how the connector seats onto the female 2 pin mic cable connector.
