No cap or ligature included. A standard size hard rubber alto ligature should fit.
I rarely see the Ernie Northway mouthpieces, but they are very good. Ernie originall made mouthpieces in Wyoming and is now in Salt Lake City where he continues to do great work. I knew someone who played one in the 80’s and she got a fabulous sound out of it.
These are some of Ernie’s early pieces, hand-crafted and much like a Meyer. This one is Serial #F492B9 with a .078″ tip.
