When were fluted headlight lens, fan shroud, and powerhouse generator discontinued?

[rusty12]

I am out of town at a friend's house and he just purchased a 1929 roadster, engine number: 1176476 which is believe is about March of 1929.

It is a nice and proper restoration but we have a few questions and my Judging Standards are at home.

The car has typical 1929 doors with exterior handles and the emergency brake lever is in front of the shifter.

The car has fluted headlight lens, red steering wheel;a powerhouse generator and original fan shroud. Are these correct for this car? When were they changed?

Thanks in advance.
