One 3 pin plug as shown.

Clean new old stock

Although these are non locking, you can use to connect many old microphones Shure, EV etc as long as cord will not be pulled on, these work fine, or add a zip tie etc to hold cord from being pulled.

The spacing of the pins is such that it can only plug in one way and is standard for many old Shure mics.

The inner phenolic body can also be taken out and used to repair microphones or replace the plug inside your existing amphenol 91-mc3m locking connectors.

Some are bulk as shown, some are still in GC electronics blister display packs that hang tags may have sign of aging

If you have a preference, ask prior to bidding.
