Two Belgium Baron Mysteries

These two photos were sent to us by Korben Guns. He writes: "I've been trying to identify these cars for a while now without success. The owner was Baron Paul van Reynegom de Buzet from Belgium.
The first picture shows the baron's first car, and according to the numberplate it's the fifth car in Belgium. Underneath the picture it simply says: 'My first car, circa 1890'. Considering there was recently an item on coal scuttle bonnets on the website some may allready know what it is.
The second picture was taken in 1913. It shows the baron's chauffeur posing next to the car. Both the car and driver were repositioned during the first world war to transport the general staff behind the river 'Ijzer'. I don't know what happened to it after the war.
Considering the Baron also bought a Minervette in 1904, the others might have also been built in Belgium."
