Horn Mouthpiece Paxman PHC 3B Cup + 3 Rim Engraving: PAXMAN LONDON 3B (Cup) 3 (Rim: White Acetal Resin) Overall, I believe it's in relatively good condition. There are some minor scratches and scuffs in places, but I didn't feel any hindrance while playing. ・Cup Inner Diameter: 16.89mm ・Rim Width: 4.20mm ・Cup Bore: 4.50mm ・Cup Depth: medium It's easy to play from low to high registers, but especially the high register is easy to play, and I think you can make the instrument resonate richly even with a relatively small amount of air. ※The rim is white acetal resin [I don't think it's currently manufactured]. White acetal resin is excellent in high strength, abrasion resistance, and fatigue resistance, and is also used as a substitute for metal. The advantage is that the temperature change due to playing is small, so the mouthpiece feels soft at all times (contributes to less fatigue and durability during long performances). Also, there is no concern about metal allergies, and it gives a softer sound impression. I think this is a rare mouthpiece that you don't see very often. If you are looking for one, or if you would like to purchase it, I hope you will consider this opportunity. ※Due to the nature of the mouthpiece, there will inevitably be minor scratches due to contact during instrument attachment, care, cleaning, and wiping. Also, I have confirmed that these do not affect the performance at all before listing it. If you are looking for a perfect item like a new one, or if you are particular about details, please consider it carefully before purchasing. Thank you for your understanding and consideration.
