This photo compares Max Keilwerth-made President tenor 51XX (bottom), with Hohner President 26XX, that he designed while working for Hohner in Germany, between 1949 and approximately 1967.
The 51XX President was built by Max Keilwerth at the time when he was working independently—after his time at Adler & FX Hüller, and before he was employed by Hohner.
