This Saxophone has a serial number that places it in the early 1920's, it is a padless (I believe that's what they call them) Artist-Model "Goldtone" . I have only been able to find out limited information regarding the Moennig Bros. Company, located in Germany. I believe they quit manufacturing Saxophones but continued making other instruments. Please help me with ANY information you may have regarding the company or otherwise. Thank You.
