Here's a very nice original American made 1930s vintage H.N. WHITE EQUA-TRU #34 mouthpiece that will fit any standard trumpet. The mouthpiece is engraved "H.N. WHITE CO. 34 EQUA-TRU" and these mouthpieces were handmade in small batches by the makers of King Musical Instruments. Original shiny silver plating is nearly 100% intact and the piece shows only light surface use. Cup and rim are smooth and comfortable and the backbore is clean. Please check out the photos. It would be hard to find another one of these in such nice original condition. Mouthpiece plays like a champ and is supposed to have a special shallow cup and an easy pressure rim. We accept most forms of payment and we also ship worldwide. This trumpet mouthpiece will be packed securely. Please check out our other quality mouthpieces listed on eBay - if you purchase several we will give a shipping discount. Excellent mouthpiece for a vintage H.N. White Co. / King collector!
