Designer: Osmun


Add a note to encourage purchase

The New York line of French Horn Mouthpiece cups by Osmun, has a moderate cup shape with the curve to the throat opening pushed down about as far as possible. It produces a large body of sound and is well suited for use with large bell horns with small mouth pipe venturis, like Conn 8D's. The New York line of cups are a faithful copy of the original Giardinelli C series mouthpieces. If you plan to purchase a rim with a cup from the New York line, note that only inch threaded rims are compatible. Made famous as the Giardinelli C series designed for James Chambers. Supplied in the traditional NY outer shape and original back bore and drill sizes.

The New York line specifications:

  • NY-C4 has a #4 bore 5.309mm
  • .650" (16.5mm) diameter at the joint where the cup and rim meet
  • inch threads are .750-36 threads, compatible with almost all American-made screw rim mouthpieces
  • multiple shank choices to fit your horn perfectly. (European and Schmid special order 1-2 weeks)
  • bright silver plated cup (gold plated cups allow for 1-2 weeks delivery)
