Here's a Harmon Three in One mute for trombone. It can be used separately as a straight mute and plunger, or combined to form a cup mute. It's in used condition with a few dents as pictured, but functional. Band Supplies currently sell these new for £74.99! I also have a Besson 600 trombone listed for sale should you be interested. Thanks for looking, any questions just ask.
