Product hard to find in silver version. Thanks to woodbrass for offering it, and at a reasonable price. Very well presented in its small thick case (but which is already useless). But I had to disassemble the octave key because the flat spring was not working properly, and for good reason, it had been bent before being installed, and therefore lacked strength. Easily disassembled, straightened and reassembled. Works normally now. Another no less surprising issue: the small pad arrived with a light stain on half of the leather. Not serious either, but the product is not cheap and one wonders what is going on in the Selmer workshop. Otherwise, it fit perfectly on my tenor bought 30 years ago, and even a little better than the original mouthpiece.
