The following information was obtained from ChatGPT: Muramatsu Flute EXⅢ (EX-III) Serial number: 62779 Made in Japan by a long-established manufacturer, Muramatsu Flute Mfg. Co., Ltd. Based on the markings on the body and included materials, it has been confirmed that this is an **EXⅢ covered key model (with Case)**. Specifications: • Model: EXⅢ (EX-III) • Foot joint: C foot • Keys: Covered keys • With E mechanism • Head joint: Silver • Body and keys: Nickel silver (silver plated) Included items/materials: • Original case • Model information from the time (with list price) ※ The listed price in the photos is ¥220,000 (excluding tax) / ¥231,000 (including tax). 【Condition】 This item has been stored for a long time and is being sold as is (assuming adjustment is required). There are minor scratches and dullness due to normal use and storage, but there are no major dents or critical damage. Sound production and professional adjustment have not been checked. *Please purchase only if you understand used wind instruments.* 【Additional Information】 The new price of Muramatsu flutes has increased significantly, and the EX series also has a stable demand in the used market.
