I find it rather hard to believe that body is from 1929, looks too modern, it even has 16" wheels, I wonder if this is not a re-bodied car?
This is just so-o-o-o-o similar to a SS90 that it must have been inspiration for William Lyons, whether consciously so or not.
And maybe the SS90 was the source of inspiration, with a touch of Talbot 105(headlamp brackets)?
Below is a picture of a 1930 FN.
