Thank you for viewing. YAMAHA YFL31 Serial number: 0031254 Head joint: Sterling silver, STERLING SILVER stamp Body: Silver-plated With E mechanism (aftermarket option) Comes with Yamaha genuine hard case When I obtained it, there was dirt and tarnish on the keys. I don't see any noticeable scratches on the body or keys. Upon close inspection, there are small dents on the head joint (photos 5, 6, 7). Upon close inspection, there are small bumps on the silver plating of the body (photo 15). Please check the photos and make your judgment. After obtaining it, I disassembled and inspected it, and cleaned and polished the body and keys. I also checked the condition of the pads. As the pads were deteriorated, I replaced all of them. During reassembly, I applied key oil and made adjustments. I did a simple sound check. I have too many instruments, so I'm putting this up for sale. The current YFL312 is made in Indonesia, but the YFL31 is made in Japan and is now discontinued. I am not an advanced player, so I cannot check the sound of all scales. Please have the key and pad balance adjusted before using it. As this is an old instrument, please refrain from purchasing if you are concerned about minor scratches or dirt. Thank you for your understanding.
