This is the Selmer S90-180, a classic model. I selected this one from seven of the same model at a music store. In addition to the responsive feel typical of the S90, this particular instrument is less prone to the buzzing sound often found in less desirable examples. I selected this one with care, but I haven't used it much since switching to the S90-190 as my main tenor mouthpiece. It hasn't been used for long, so the logo is still in good condition. I was keeping it, intending to use it if I went back to the 180, but I think I'll stick with the 190 for a while, so I'm putting it up for sale.
