Without a doubt what makes H. N. White instruments unique is their use of Sterling Silver Bells. Some time between 1925 and 1928, The H. N. White Company introduced the "Silver Tone" Sterling Bells option to Liberty Trumpets, Master Cornets, Clarinets, and the entire Trombone line of instruments. As stated in the 1928 complete catalog, "Sterling Silver Bell produces better tone, being clearer, richer, and more resonant, with a more pleasing quality." The engravings on "Silver Tone" instruments are some of the most elaborate and attractive works of art ever produced by an American manufacturer. A short time after World War Two (1949-1951), "Silversonic" replaced "Silver Tone" and the engraving was not as elaborate (except on Artist level), but the quality of tone remained the same. In addition, Saxophones were give the option of having a Sterling Silver Bell with the introduction of the World Famous "Super 20" and later "Silversonic Super 20", which were some of the most sought after production saxophones ever made.
According to popular folk lore, it is thought that F. A. Reynolds was the designing force behind "Silver Tone" bells, this rumor has never been proven. On large numbers of promotional literature from the mid to late 1920's, H. N. White is credited with designing most of the instruments with Silver Bells. It is not known whether or not this was due to H. N. White owning the company, but what is known is that Mr. White was very involved in the designing of all new instruments and or any new features of an existing instrument.
