Up for sale here is this small lots of parts for Amphenol 91-MC3M 3-pin and 91-MC4M 4-pin microphone plugs and jacks. You will receive all the parts in the pictures. These are used and in decent shape, but some do have some rust on them. Some of these are fairly complete and others are just parts. There are no complete mic plugs included, just these parts. Please see my pictures for details.
