Vintage Conn 40B Trumpet

A beautiful Conn Trumpet from the 1930's (likely 1932).  Silver-Plated with a gold wash bell, fluted valve casings, underslung slide ring, discreet water keys, Vocabell (rimless bell)

What Conn said in 1933:
The most popular trumpet on the market. Used by such first chair stars as Lebert Lombardo (Guy Lombardo), Jack Cavan (Charlie Agnew), Lamar Wright (Cab Calloway), Charlie Williams (Duke Ellington), David Glickstein (Broadway shows) and Eddie Camden (Don Bestor). The Vocabell rim is a single, integral piece of metal which allows it to vibrate freely. Conventional bells have a rigid wire in the rim which tends to muffle the tone and dampen out the delicate harmonics that are so essential to clear tone and rich coloring. Delicate instruments of Columbia Broadcasting Studio in New York show the Vocabell has from 12 to 15 decibels greater volume, is smoother and more even in scale, and is clearer and purer in tone than trumpets with the conventional type bells. Beautifully styled in modern manner. Medium bore.
