"SYW Hessian foot and artillery" Topic

I'm just getting started on my Allies, Hessian, Hanoverian, and Brunswick. My main resource is Kronoskaf which is great but they were a little vague and actually conflicting on certain articles of clothing. Gaiters, for instance, Normally white for summer and black for winter. Some of my other sources just show black gaiters. Wouldn't white be only for parade and summer with black being the norm while on campaign, even in the summer?
Also, does anyone have info on artillery uniforms? I have a number of the artillery figures with their coats off working in shirt sleeves, apparently. What do they normally wear under their uniform coats?
Finally, their is scant information re: Hessian flags, I found and old source showing some that are believed to be from the period. They showed two flags both with a stylized "W" over crossed laurel branches and surmounted by a crown, one on a white field, the other on a purple field?

Info on the Hessian flags is quite confusing and mostly unknown. The Pengel and Hurt booklet dealing with Hesse Cassel has a couple of drawings.
The 'early' flags are the stylized W as you mention. Regimental for Capellan is orange. Leibfahne for Mansbach is white.
A second type is the Hessian striped lion surrounded by a gold circlet on a field of blue/red/white flames for Regt. Erbprinz.
The third 'later' deign is the Hessian lion surrounded by wreath plus scroll and crown above. Crowned monograms in the four corners and flaming grenades on the four sides. This type is shown on the Sturm cigarette cards for Regts. Prinz Carl and Ysenburg:

P.S. The next page shows an Artilleryman with blue waistcoat and white shirt beneath.

There is a fair amount is known about the Hessian's and Hanoverian, but Brunswick is another story. There has been a couple of postings on Hanoverian and Hessian (red & white) gun carrages, but there is little to nothing on Brunswick.

Brunswick artillery was very limited and made up of many lighter type guns. As to colors, The late war ones are know and presented in Kronoskaf The earlier ones are subject to speculation as very little is known. One source has the Dukes Monogram surrounded by a wreath and surmounted by a crown on one side and the Brunswick running horse within a wreath on the other. Back ground color of the company flags may have followed the same as the later colors'. The Lieb Standard may have been of the same design on a white field.

Know this is late, but here is my conjecture of Brunswick Lieb Standard. As to scourges for this, well honestly I've forgotten them.

Two things, firstly I'm afraid your link is Kaput. Secondly do we have any evidence that the uniforms are anything other than made up. I'm not sure I regard the SturmAbteilung that highly when it comes to academic excellence.

Not sure how accurate the Sturm cards are but there are other pictorial sources available. ie Gallica has number of books of plates on the Hessians.
