not at the moment,to be honest these are new to me were they common in the Prussian army throughout the war or were they only present in certain regiments.
I have the Kuhn/Hall work on the army of Brandenburg Prussia. Apparently the cassock was pervasive and could be found in Flanders up until 1710. The split cuffs (I'm sure there is a name for that) was present on the coats of some regiments and not on others). If you're going to do figures for Prussians you might want to get your hands on the Kuhn/Hall book.
