Trombone - King 2103 (3B) Silver Sonic (SGX) Excellent condition!

This is King 3B Silver Sonic, in excellent near-mint condition. I believe it is a product of 1990s. Slide is like butter, and has a custom leadpipe made by Chuck McAlexander at Brass Lab in NYC, for more open feeling. No dents anywhere. Price includes the shipping to lower 48 states. Please contact me for shipping cost outside of it. Pictures available by request. This is a fantastic horn!
