Hello and welcome to The House of Chrome.

 You are looking at a desirable 99G86 Controlled Magnetic element made by Shure Brothers in the late 1965 and known as the white label model. These elements were made for years and were originally sold with entry level microphones primarily used for dispatch and general broadcasting purposes. This is an early C.M model.

 Today these make excellent harp mic elements due to their smaller size and dirty, muddy tone.

 As you can see right away the writing on the rear of the label is very faint and almost completely faded away though this is a 99G86 / 850 set at High Z. 

 As you can see this element looks very good and there are two wires protruding from the side which is a positive and negative that can be easily soldered to any other wiring.

 The element is appx 1 5/8 inch across X 1 inch deep. These elements can be used in most vintage mics from over the years.

 The signal strength is 100% with zero issue. Strong and clear...ready to go.

 Priced very reasonably as well.

                         As with all my vintage microphones...
