This gray automotive paint color is most commonly known as Lockhaven Gray. The only reference of this paint is in a "Ditz-Lac Intermix Formulae" chip book from 1939 (note: this is a cool book with all Ditzler IM prefix paint codes from 1928 to 1939 with updates for later years). See the detailed list below.
IM1004 is a paint code for PPG (Pittsburgh Plate Glass) who has been providing automotive paints since 1924 (originally Ditzler Color Company subsidiary acquired in 1928). PPG/Ditzler codes starting with the letters "IM" indicate Ditz-Lac colored lacquers and polychromatics (fine aluminum powder added) and were used before 1940.
