For sale is Guardala largest, most collectible and rare three-figure mouthpiece, the Crescent Model David Liebman. This is another mouthpiece from my collection of Guardala mouthpieces that I have collected over the years. This is one of the first mouthpieces Guardala ever made and it is rare to get one of his first pieces for David. Never improved. The bite block may have been replaced by the original owners. This is the best game I have ever played!!! Killer!!! Excellent altissimo and good low frequencies. Without ligature and without cap. Delivery to all countries. Please ask questions. Good luck in battle friends!
