{"product_id":"trombones-m14386223622","title":"Trombones","description":"\u003cp\u003eThis rotary assembly is designed for trombone enthusiasts and collectors. It was originally intended to modify Yamaha custom trombone F attachments, such as those from the 8420 and 8425 series, by adapting the rotary valve to a Conn-style wrap similar to models 648 or 643. The assembly combines parts from discontinued models, including a rotary valve joint from the 8425G2 and components compatible with Zeno designs.\u003c\/p\u003e\n\n\u003cp\u003eAlthough the project to complete this modification was never finalized, the assembly includes a rotary casing with re-drilled screw holes and a damper rubber base repositioned for ball joint compatibility. The rotary cap is from a Zeno trombone, and while the lever is not included, it is likely compatible with current Zeno levers. This item is new and unused, offering a rare opportunity to acquire valuable parts for specialized trombone customization.\u003c\/p\u003e\n\u003c!-- ai_desc:v3_richer_natural_descriptions --\u003e\n\u003cp\u003e\u003cstrong\u003eShipping \u0026amp; Authenticity\u003c\/strong\u003e\u003cbr\u003eAuthentic item sourced from Japan.\u003cbr\u003eInternational shipping with tracking.\u003c\/p\u003e\n\u003c!-- mercari_url:https:\/\/jp.mercari.com\/en\/item\/m14386223622--\u003e","brand":"Unbranded","offers":[{"title":"Default Title","offer_id":53805503512923,"sku":"b587cc5cb7f600808492793828547415","price":289.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0973\/9557\/3083\/files\/b587cc5cb7f600808492793828547415.jpg?v=1786992404","url":"https:\/\/japan-items.com\/fr\/products\/trombones-m14386223622","provider":"JAPAN-ITEMS™","version":"1.0","type":"link"}
