Condition & Setup

The satin body surfaces and polished keywork show widespread age-related tarnish, dulling, spotting, light scratches, and localized finish wear, including a pronounced horizontal abrasion around the bell throat. The neck cork shows visible wear and discoloration, and the included soft case has dust, scuffs, and general exterior wear.
Who the Semi-Rationale Alto Saxophone Is For
This instrument is best suited to experienced saxophonists, collectors, and specialists interested in historic French saxophone design and unconventional mechanical systems. Its extensive linked keywork offers a distinctly period-specific playing interface rather than contemporary standardized ergonomics, making it particularly relevant to musicians who appreciate unusual mechanisms and are comfortable becoming familiar with a specialized key layout.
