Re: JW YORK AND SONS SAXAPHONE
York made their own horns, and some were Conn stencils (earlier horns). My guess is that yours is of early 20's vintage, and like sax mom said, it's a Conn stencil. Probably a New Wonder Series I stencil. Does it have rolled tone holes (the area where the pad touches the tone holes is rolled to form a lip) Most of the York saxophones that the company produced themselves were also modeled after Conn horns.
