my research reveled :

• The model number AI-412 on your Conn Visible Embouchure mouthpiece identifies it as the Ernest Pechin custom signature model designed specifically for the cornet. During Conn’s "Famous Artist Era" (roughly 1914 to 1935), mouthpieces were stamped using a highly specific alphanumeric system to designate their instrument, artist profile, and material composition.

Who was Pechin?This model was custom-tailored to the specifications of Ernest Pechin, a premier virtuoso cornet soloist of the early 20th century who famously performed with the Innes Boy Scout Band, the Thaviu Band, and as a featured soloist for the C.G. Conn company itself. Because it was a specialty artist model rather than a standard student size, the AI-412 is highly sought after by vintage brass collectors and is considered a very rare piece today.

The Conn Visible Embouchure mouthpiece is a highly collectible vintage brass mouthpiece introduced by C.G. Conn in the late 1920s, featuring a distinctive removable translucent cherry-red Bakelite cup screwed onto a metal stem.

History & Patent Details

• The Invention: Patented by Edward Gulick for C.G. Conn, the official design patent (#1,740,013) was granted on December 17, 1927.
• Pat. Applied For" Stamping: If your mouthpiece is stamped with "Pat. Applied For" or "Pat's App'd For" instead of a patent number, it is an early production model manufactured between the 1925 and late 1927 before the patent was officially approved.
• Marching Advantage: Beyond training, the resin rim was favored by marching bands because Bakelite retained warmth and did not freeze against the player's lips in cold weather.
• Cornet Models: Commonly referred to by collectors as "cherry tops," these utilize a shorter cornet shank configuration.
• Condition is King: Because old Bakelite degrades, becomes brittle, or cracks when dropped, units with 100% flawless, uncracked red inserts command a significant premium.
• ( mine in very good no degradation )
• Plating Upgrades: Standard models feature silver-plated or raw brass shanks. Rare versions featuring intact gold plating on the metal stem are highly coveted by vintage instrument collectors
• The model number AI-412 on your Conn Visible Embouchure mouthpiece identifies it as the Ernest Pechin custom signature model designed specifically for the cornet. During Conn’s "Famous Artist Era" (roughly 1914 to 1935), mouthpieces were stamped using a highly specific alphanumeric system to designate their instrument, artist profile, and material composition.
• "A" (Instrument): The first letter indicates the instrument category. In Conn's catalog, A stands for Cornet
• "I" (Series): Represents the styling and blank profile of the "Famous Artist" line.
• "412" (Bakelite Configuration): Model numbers in the 400s denote a Visible Embouchure mouthpiece built with the signature translucent cherry-red Bakelite cup.
• he AI-412 Ernest Pechin signature model is much rarer than standard trumpet versions like the BI-420. Its estimated market value depends heavily on the condition of that translucent red Bakelite cup: Flawless Condition ($175 – $275+)
• note *****(MY top is in pretty much flawless condition see all pics)
• NOTE ****( I am pricing mine very reasoanable for being in very good condition 200 free ship )
• The Cup: Completely clear of hairline cracks, chips, or deep scratches, and safely screws tight onto the stem. ( check mine is this )
• The Metal: Original silver or gold plating is mostly intact with minimal wear on the cornet shank. ( check mine is this )
• Value: This tier commands a high premium from collectors of vintage C.G. Conn memorabilia because artist-model "cherry tops" are incredibly difficult to find intact.
• (mine priced 200 plus ship)
