Reference Notes
JK SM3 appears in the French Horn catalog section with 17 mm rim, Medium cup, 4.2 mm bore, and standard shank. Database tags list it for Orchestral and Classical use. Noted features include Artist Model. Use these measurements as a comparison starting point: fit and response still depend on the player, dental structure, instrument receiver, and each manufacturer's measuring method.
