Here's what I presume to be a York-made (non-stencil) York bari. Notice the oddly-soldered tone holes (with bases or "spats"), visible on lower holes, as well as plate on main body with the remainder of the holes--uniquely York. They apparently had a full line of horns, given this bari, the curvy sop that vintagesax has on their website: http://www.vintagesax.com/soprano.html
as well as altos, tenors, and c-mels. Anyone seen a non-stencil York straight sop?
