RG&JS 15-8 Revised 1997
A blue vitreous enamel emblem was used on the 1928
through 1930 radiator shells. The non-enameled
portions were unpolished nickel plating through 1929
and dull chrome thereafter. The 1928 emblem had a
stepped edge, whereas the 1929-1930 emblems had a
chamfered edge. With the introduction of the 1931
style shell the emblem was changed to a stainless steel
stamping with black paint in the recesses. Some
stamped emblems used between late 1930 and March
1931 had blue paint in the recesses.
