After faffing about with this for aeons, I've decided it will have to do as it is. This is the older style of Prussian dragoon standard, dating from the reign of Frederick's father, Frederick William, and it has his monogram in the corners along with the older style of central motif. It was the style carried by the 1st, 2nd, 3rd, 4th and 7th Dragoons. This motif shows an eagle flying towards the sun with the motto "Non Soli Cedit"; "He does not give way to the sun". This symbolism represents the Prussian eagle versus France or at least the French monarchy, I believe.
