Here is an original condition Otto Link Tone Edge alto mouthpiece. This piece measures .063" on my gauge.
Tone Edge Links from this period offer a warmer alternative to the ubiquitous Meyers of the same era. This piece survived the decades with only a little discoloration and a few small marks. This particular one has a wonderfully crafted rollover baffle at the tip and speaks very quickly.
This piece would be fine for someone who wanted a larger chamber piece that is easy to control or would be suitable to open to a more contemporary size.
