The Conn 10B New Era has a medium bore (#1½). When new in 1935 it sold for $100--equal to approx. $2,350 today.
Serial # 305159
It’s condition is "good" and I like the way it plays.
From Conn: “The 10B is a narrow, streamlined, racy looking model which is much in demand by those who want modern design. Although long, it is well balanced and easy to mute. Its tone is big and powerful and brilliant. Medium bore. Equipped with Clickless Crysteel valves.”
Prior to my ownership, it looks it has had some modifications that are evident in the pictures.
Some silver has worn off in the usual spots and there are a few minor dents also visible.
I can add a mouthpiece if needed and if you want, the case pictured can also be included.
This "pea shooter" plays well and only selling because I have collected too many horns of the years. Message me with any questions except "Is this still available?" If posted, it's available and I will promptly remove upon sale.
