Derby Mutes, Six Stone Lined by Humes and Berg

Description

Here is a find from my retired Big Band Days.  Six  Humes and Berg Derby Mutes.
Som
e of them have a quarter inch hole in the brim to attach to a music stand. About twenty-five  years old.  I would say they are in good condition.
One does show some felt wear and another more so.  Take a looks at the pictures.  You have wanted Derby mutes for your band, well.... here they are!
Thanks for bidding.
