<h2>Rare Muramatsu AD Model All-Solid Sterling Silver Concert Flute - Late Production 50,000s Serial [Silver Engraved Stamp / Untested Raw Estate / As-Is]</h2>

[Product Overview]

For your consideration is one of the most prestigious vintage professional instruments in Japanese flute-making history: The Muramatsu "AD Model" All-Solid Sterling Silver Concert Flute.

Positioned historically between the DN Model and modern DS Model, the AD Series is globally revered by orchestral artists and soloists for its dark, velvety tonal core, immense dynamic range, and immaculate key mechanics.

Constructed with 100% Solid Sterling Silver (.925 Ag) across the headjoint, body, footjoint, and key mechanism, this flute features the authentic "SILVER" hallmark stamp engraved on the body tube.

[Serial Number & Production Heritage]

- Desirable Late Era Serial: Features a desirable 50,000s serial number (specifically 59,000s range). 

- Historical Context: Production of the AD Model concluded around the 60,000 serial range. Instruments in the late 50k range represent the pinnacle of AD manufacturing, benefiting from Muramatsu's most refined pad mechanics and silver craft before transitioning to the DS lineup.

[Condition & Sales Terms]

- Functional Status: Sourced directly from a private estate. As the seller is not a flutist, musical sound testing has not been performed ("演奏確認は出来ておりません").

- Physical Condition: Visually appears remarkably well-preserved with smooth key action and normal light silver patina/tarnish consistent with careful storage ("保管状態は良好").

- Terms of Sale: Offered strictly "As-Is / Untested Condition". Standard pad adjustment, seating, or routine technician setup is expected by the buyer for professional concert play.
