This is a King 2B Silvertone (now Silver Sonic) from the H.N. White era. It's a legendary instrument that Tommy Dorsey loved. According to the serial number, it's from around 1940-1945. When I bought it, I compared it to a Silver Sonic, and this Silvertone was about 150,000 yen more expensive, but I chose it because it played so much better. It's a truly wonderful instrument, but I no longer have a use for it, so I'm putting it up for sale. If you're in the Kansai area, you can try it out. Thank you for looking.
