Gentlemen,
I'm tumbling in:
I remembered that I have two books on the shelf that might be of some interest to you !
Both in French.
1. Casques et coiffures militaires Français (Christian H. TAVARD)
Jacques Grancher
2. Les uniformes du premier empire, Les Cuirassiers (Cdt BUCQUOY)
You can contact me (PM).
Rgds,
Francis
