fourth and fifth row: both Star and Triumpf tenors were probably build by Julius Keilwerth and might be assembled by a so called ''Fertigmacher'', who used FXH parts ? ( bow guard on the Star, neck and bow guard on the Triumpf ). I've seen a 1939 Tone King solo tenor with the ''JKG best in the world'' stamp which except for the bow guard and engraving was the excact same horn as the Star!
sixth row: Zenit alto ( 3rd period FXH stencil ) source bazos.cz, both the bill and the warrenty card dates the serial number 24378 back to march 1940
seventh row: Benny Carter alto ( late 2nd period FXH stencil )
eight row: Klingson saxophones  were built for Hammerschmidt during the entire FXH saxophone production. All models were stenciled, from "Professional'' to ''World de Luxe''.
Even the very rare extraordinary late 2nd period F.X. Hüller alto was stenciled for Hammerschmidt and called Klingson ( see playing page ).
