Historical Overview: Conn began producing a double-walled metal clarinet just a few years after the first saxophone was made in America (1888). Couesnon presented a double-walled Boehm System clarinet in a Paris Exposition in 1900. Triebert also came out with a copy of the Couesnon. Around 1910 Penzel-Mueller (NY) started making the double-walled Clari-Met line to be offered at a price of $150-$200, and was perhaps the most expensive clarinet available at the time. According to the manufacturer, the Clari-Met, made of a special alloy that was almost sterling was destined to make wooden clarinets obsolete. By the mid 1920s there was little interest in the very complicated manufacturing process to produce a clarinet that cost half as much as an automobile. Then in the late 20s Conn began making the "Armored' clarinet, a double-walled model filled with hard rubber. And finally Haynes started producing a double-walled sterling clarinet which is said to have caused heated debate within the company, and less than 400 were made. Somewhere along the line Selmer also made a double-walled sterling model. Value of these instruments covers a wide range because, although they are rare, and often high quality, if they are damaged they might be unrepairable.
