Laskey Trombone Mouthpiece 54M Large Shank Silver Plated Rim: 25.4mm Bore: 6.73 This is a slightly older Laskey mouthpiece. The rim is clean. The shank has some scratches from insertion, but overall, I think it's in good condition. There are no dents. I'm selling this to clear out some equipment during the Obon holiday since I don't use it. However, I'm still hesitant, so I might withdraw the listing.
