Archive Notes
Standard Rim. Same as Cushion Rim No. 21. Historical source note: Brass History documents Rudy Muck Cushion Rim mouthpieces from the early 1930s through later 1940s and 1950s catalog styles. Trumpet/cornet labels are preserved as catalog context; matching model numbers can appear across trumpet and cornet lines. 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.
Vintage source note
Rudy Muck trumpet/cornet labels are historical catalog context
Brass History documents Rudy Muck Cushion Rim mouthpieces from the early 1930s through later 1940s and 1950s catalog styles. Where model numbers appear across trumpet and cornet lines, BrassFit treats the instrument label as catalog context rather than a hard sizing boundary.
