Thank you for the point, at first I ruled out Vauxhall because it seemed to lack the very distinctive bonnet flutes, but on closer look they are very much there, and the mascot is unmistakable.
Vauxhall's model denomination can be quite confusing and seems to vary according to the source.
I have found the car below and it's said to be a 1930 Vauxhall 20-60 Kingston Coupe
