Further review would indicate your source is correct, it is a 1939 model, not a 1940.
The two photos posted show that on the 1939 model the two chromium strips on the motor hood are the same length and on the 1940 model one strip is shorter. Sometimes difficult to see looking at a photo taken from an angle like yours.
So, continuing on, is the coachbuilder Dutch?
Edit: And you think you are having a bad day!! It is only 1400 hours here and I forgot to attach the photos.
