Selmer Signet Harry James design Prototype "S" 1943 H & A Selmer trumpet For Sale

Professional trumpetRare 1943 H&A Selmer "S" Brace Prototype – The 'Harry James' Model
Serial No. 3972 | Made in Elkhart, Indiana
The Collector’s Overview
Offered here is an exceptionally rare artifact of American brass history: the H&A Selmer "S" Brace Trumpet. This instrument is an original production prototype, famously associated with jazz legend Harry James and featured in his 1941 Trumpet Method book. 
History suggests that only 10 to 15 of these "S" model prototypes were ever manufactured in Elkhart, making this one of the scarcest Selmer variants in existence. For the serious collector, this is a centerpiece acquisition. 
Performance & Tone
Unlike many museum pieces, this trumpet is a formidable player. It delivers the high-compression, "strong and loud" projection required for lead jazz work.
• Character: Brilliant, resonant, and incredibly responsive.
• Slotting: Exceptional intonation across all registers, true to the professional-grade craftsmanship of early 1940s Selmer.
Condition & Specifications
This horn has a storied history and the "player’s patina" to prove it. As a collector, I believe in accurate representation:
• Dimensions: 19 1/8" total length; 4 ¾" diameter bell. 
• Finish: Shows honest vintage wear, including lacquer loss, scuffs, and rubs.
• Body: Minor dings present, consistent with a vintage instrument that has been actively played and loved for 80 years.
• Functionality: Valves and slides are in good working order; this horn is ready for the stage or the archive.
Proven Authenticity
This is a genuine H&A Selmer Inc. professional-grade instrument. The unique "S" bracing is not just a visual signature but a testament to the experimental design phase of the early 1940s.
Includes: Period-correct hardshell case.
