Be warned the plates on artillery equipment are dubious at best. The poles use a lot of Prussian guns re-bored, but the illustrations of Prussian guns are the post Napoleonic type. The French equipment drawings are all pre the 1789 changes to Gribeauval and the AnXI/1807 guns, bar a solitory French AnXi 6-pdr, which is again dubious in its depiction.
What I have read of the text via a friend who translated it for me, seems well researched
