Paul, are you aware of the works of the French 19th century artists Eugene Titeux and Auguste de Moltzheim? They are the masters of Restoration uniforms in my opinion. I have 4 original Titeux prints. They are wonderful. Although Bertrand Malvaux sells them, he is quite pricey. I bought mine from: Soldaademohler | Objets d'Histoire & histoires d'objets They are great to deal with. As an aside,
you really must visit La Musee d'Armee in Paris.
