Apparently this kind of vehicles were famous in High class society ladies, at that time. This one in particular had suffered some modifications, that's why the article about it. I don't know who built it, I just know that this lady's name and the name was given to the vehicle. All the pictures that you post, shows the same lady with the same car.
Her husband's name was in the article, but there are more than 5 Stuart Duncan: Banker, Airplane designer, Musician, Architect, Dentist, etc. Anyway, all I need to know is this vehicle's given name.
To simplify as I said before, the name is just the description of what it is.
