These figures were 3d printed. I backed a Kickstarter from Napoleonic STL Files, David Vazquez Fernandez, " Prussian Infantry".
I painted them as the 1st East Prussian No 1. From 1808 to 1815. I followed the information I got from the book "The Prussian Army During the Napoleonic Wars (1792-1815) Volume 1" by George Nafziger.
