I've cut and pasted this from a previous post so don't think your going mad if you've read it before!
Uniform and flag sources, I have access to all of August Kuhn's plates, unfortunately getting them is like finding rocky horse poo.
Also I obtained (Heft 16) Hessen-Kassel 1701 - 1714 by Claus-Peter Goldberg & Jean Belaubre copyright 1995.
My son speaks fluent German, I'm a Northumbrian so hardly speak English.
I also have all of the other ones covering the German states of this period. Try to get hold of these they are very good and worth having.
As another poster on this forum says, secondary sources, but frankly who has the time to dig out the originals.
The flags are for the most part as accurate as I can get then for 1704 (they changed later in the war) but even given the above sources some are my guestimates!
I have seen Hessen-Kassel troops beautifully painted on here before with flags seemingly based on the later Seven Years War flag of the state, they may or may not be accurate, you pays your money and takes your chance.

And the whole Major General Wilkes Hessen Kassel contingent present with Cutts' assault column, Grenadiers to the rear:
