To Mr. Hokkairolen, Thank you for your patience. I have crafted this as closely as possible to your specifications. Shinobue (Japanese bamboo flute) - Classical style, Key of C (3-hon choshi), 7 holes Tenchi-do (top and bottom) wrapped with rattan Smoked finish Ultra-Iron specification (thin aluminum plate wrapped under the rattan for increased volume and sharpness) Coating: Cashew lacquer Inner tube painted black Total length: 492mm Thickness near the utaguchi (mouthpiece): 21mm Utaguchi (mouthpiece) dimensions: 12.5mm x 10mm Finger holes: Approximately 8mm Thickness at the kanjiri (end of the flute): 19mm Inner diameter at the kanjiri: 13.5mm The length from the utaguchi to the finger holes is based on the measurements you provided. I have begun making Shinobue flutes. The flutes I am making are based on the flutes of a famous flute maker in Chiba Prefecture. I use Chiku (dwarf bamboo) from Minamiboso, Chiba Prefecture. I am creating Shinobue with a slightly unique atmosphere. I am making Shinobue under the brand name "Namiichi". I will only conduct transactions with those who can complete them within 24 hours. I have uploaded images of the manufacturing process on Instagram. Please take a look if you'd like. https://www.instagram.com/namiichi.sinobue?igsh=MWl3OGRzaXhpaGNvMg==
