Here is an original condition, 1960's Otto Link Tone Edge 5*, with the name written on a slant. This mouthpiece measures .060" on my gauge.
The average post 1950's soprano mouthpiece typically has been influenced by the small chambered Selmer Soloist design. But for players looking for a more unique sound in the vein of luminaries such as Steve Lacy or Wayne Shorter, the Otto Link design offers something unique. With the chamber not being as large as the typical American design, this piece can actually center up with a nice amount of flexibility afforded the player.
For someone looking for a rare design, in amazing original condition, this is a great size for this chamber.
