I prefer my custom old French entitlement Bronsvic Régt. Du Corps. As can be seen, I opted for the old flag design documentsd to around 1754. I like it so much more then the "prussianized" design introduced after 1754 (see kronoskaf). However, the oldest illustration of the new design seems to date no earlier then post SYW, I believe. The smoking gun proving the new design was around by the SYW is missing, really. It is just speculation based on the reorganization from 1 battalion to Prussian style 2 battalion footing, which also demanded for new sets of flags. It is generally believed that also the new flags were introduced at the same time. A very just assumption, but I so much prefer this rather classic "Protestant German" flag design. It matches so well with that of the Hessians, as well of my last year's raised Saxons in 7YW French service.
Earlier, I did the regiment von Behr (red flag), and I gave one stand of my old regiment von Imhoff a new flag (green) and black gaitors.
The unit seen in the upper left background is my second stand of Imhoff that I will convert to regiment von Zastrow with yellow facings and a yellow flag.
And while I was engaged converting some Brunswickers, I also took the effort to repaint 2 of my Hesse-Cassel infantry flags.
Its the regiments Prinz Wilhelm, later Erbprinz, IR12 (light blue flag) and the Grenadier Regiment later Zweite Garde, (yellow flag).
More new painted as well as remastered Hessians are to follow within soon.
