This auction is for both the cup and the straight mutes.  They are vintage "New Stone-Lined" Humes and Berg mutes for trombone or baritone/euphonium brass instruments.  They have been gently cleaned and come from a smoke free, pet free home.

Please note that the cup mute is missing one of its corks.  It also has some writing on the red part of the cup.

Please take a look at my other auctions to save on shipping when more than one is won.                             
(I also have an aluminum straight mute on auction.)
