Hi ! I have found some information on this fantastic blog :

"Dutch Cavalry Regiment No.10 formed in 1672
This cavalry regiment would be Lodewijk Christiaan Graaf van Wittgenstein in 1674, possibly present at the battle of Seneffe 1674. In 1676 the colonel was Albert Ferdinand Graff van Berlo.
Uniform details & sources: Gerpines andd Wagner agree on the facing colours (red cuffs, red waistcoat, red breeches), Wagner and Belaubre say the coat was a dark grey colour. The shabraque was red laced white (silver lace for the officers). A white flag would be the Colonel's/Regiment's flag, a green flag for the squadron.
The officers jacket is red laced silver, the trumpeters jacket a brown colour (burnt sienna) with white hoops on the arms, the trooper's jackets are a darker grey. I have added a few with buff coats for protection. All wear the orange sash to denote service in the army of the the United Provices.
I haven't found the motto for the flag yet, I'll add the lettering if I do. I'm acquiring a copy of Wargames Illustrated #173 february 2002 with Mark Allens article on William III Dutch cavalry.
Just figured out Mark Allens handwriting the motto is 'PACEM ARMIS QUERO' loosely translated as: 'peace by force of arms'."
I hope you will find it somehow useful .
