C.G. Conn Model 12M Baritone Saxophone Overview
The C.G. Conn Model 12M is a vintage American baritone saxophone, offered here as an "as-is" restoration project instrument that is not playable in its current condition that will require a complete overhaul before musical use. This later-production 12M features nickel-plated keys and straight tone holes, reflecting Conn’s postwar baritone saxophone design lineage. It is best evaluated as a restoration candidate for a technician, collector, or experienced player seeking a rebuildable Conn baritone saxophone rather than an instrument for immediate performance.

Who the Model 12M Baritone Saxophone Is For
The C.G. Conn Model 12M is an Eb baritone saxophone intended for players, collectors, or repair technicians who value vintage American saxophone design and are prepared to complete a full restoration.
