1Evidently not available for Delux-tone models. 2Details not available on leather upholstery in Delux-tone models. 3Radios must have been a hot item in 1940, for by the end of the model year, Studebaker was out of the AC-910 radios.  After September 5th, 1940 a substitute radio was offered for 1940 Champions. This was discussed in Parts Department Letter No. 587. 4Studebaker sold them to dealers for $12 and suggested dealers sell then for between $19.45 and $21.45, or use them for prizes, bonuses or sales enticements.   Studebaker itself actually offered them as prizes for various contents. 5This is a case where Studebaker used the same AC number for different items. 6Standard on Custom DeLuxe and Delux-tone models. 7Used in conjunction with AC-926 bumper guards.
