These are lovely sounding horns. The key work isn't up to the level of the later Committee and The Martin models, nor is the intonation, but nothing that one can't learn to overcome with minimum fuss. Martins are some of my very favorite horns, and they were really built to last. Martins, like Kings and Conns, require a thinner pad (.160 or so), and benefit from plain flat metal resonators (like, but not limited to, the Conn Reso-pads.), or the Selmer Brown plastic dome resonators. Nothing that is going to destroy that beautiful, dark, lush tone. I'd recommend Steve at World Wide Sax, Dave at Junkdude, or Gayle at Vintagesax for restoration and setup of these horns. All do a top quality job. You aren't going to retire on what you make on these should you desire to sell it. These rarely go over a grand, even when Silver plated, unless they are mint/extra fine condition and possess unusually elaborate engraving.
