Someone here might buy it.
In case you are interested in this period of the French army, it is a must have - the download by foundation napoléon - is in black and white only.
There I am a no zoner, I have no access to Hathi, it would be interesting to know if that download has the plates in colour as well.
I own an original copy - I was lucky enough to snatch it on a flea market in Paris.
Hollander's work is excellent and is highly recommended.
