Up for sale I have Warburton 5MD top (silver) £30 Warburton 5BD top (white delrin plastic) £20 Warburton 5S top (silver) £30 Warburton 8 cornet backbore £20 Only selling them because I have changed to size 4 rims. These mouthpieces served me well for all sorts of gigs from big band to brass band and on soprano cornet! Having both the 5MD in metal and plastic is great for winter, you get pretty much the same response from the white delrin mouthpiece as you do on the metal pieces. email@example.com Do get in contact if you would like photos sent to you. With the way mouthpieces has increased in price this is an excellent deal! Thank you for stopping by.
