Thank you for viewing. Please read the profile before purchasing. Thank you. JK Horn Mouthpiece Will Sanders Model SF3 17 3/4M Used Silver-plated finish Rim inner diameter: 17.75mm Throat diameter: 4.3mm Cup shape: U-cup I purchased this new from a musical instrument store several years ago. It's in beautiful condition as it was only used for testing. I used it with a European shank instrument. The current retail price (including tax): 19,250 yen, and it seems to be sold at a discount for around 14,000 yen. I will also include the original paper box and the included mouthpiece brush (unused). I am selling this at a special price personally to clear out mouthpieces I'm not using, so I will not be offering any discounts at this time. Thank you for your understanding. Returns and refunds are not possible. Please ask any questions before purchasing.
