1933 Model 56 St. Regis Brougham, starting resto - need specifics, colors

[dc8ups]

Hello! Just starting my resto. Wondering about the radiator shell and the thin vertical grille strips. I am assuming that the shell is chromed, although when I got mine it was painted silver. As for the vertical strips, are they chromed, painted one of the exterior colors, or painted black? or possibly some other color? Next topic, my floorboards and toe boards are basically missing. There is some wood there but it is plywood, and badly deteriorated. I am assuming that the original board were either oak or ash, but I am not sure. Thoughts? Also, were there any kind of ribs or frames as well for support? Thanks in advance! Scott
