Pete Thomas / Ed Pillinger Onyxite (.050) Large Chamber Soprano Saxophone Mouthpiece
This looks to be a Pete Thomas or Ed Pillinger Onyxite Soprano Saxophone Mouthpiece. I believe Ed made these for Pete. Most of the markings have rubbed off. The table is marked, "125". This is a large chamber mouthpiece with curved inner walls. The tip opening measures .050. Excellent condition.
