Here is GM/Chevrolet documentation regarding the locations of various "ID" tags/plates/information: 1936-1962.

I'll look for pre-1936 ID information.

Added later:
1935 is the first year that I can find GM stating the use of an Engine Serial Number and a Vehicle Serial Number (locations are not described).
