HARMON MUTE Cork Trumpet

This is a cork for a Harmon mute.

Because the size varies slightly depending on the era, after you purchase, we will ask you to measure a specific part. We will ship your order once we receive your measurement.
We want to send you the closest possible fit, so we appreciate your cooperation.

The third photo shows it attached to my own Harmon mute for your reference.

These are made by an amateur as a hobby, so I am offering them at a low price as a way to share. If you are looking for high quality or precision, please purchase a commercially available product.
