Wow, very cool! That's awesome you're able to get information on the name too. Quite a number of significant battles the 12th was in, even in just the period that Nicolas served.
Hope you're able to purchase it, if you decide to do so!
Pretty sure I will. A "Charleville" (which is what this one is, although made in St Etienne) and a Brown Bess are the ones I was hoping to add to the collection this year. Once I do I'll post pictures here.
And yeah, the 12th has quite a record - from 1808 onward:. 
1809: Thann, Abensberg, Eckmuhl, Ratisbonne, Eugerau and Wagram
1812: Wilna, Drissa, Witepsk, Smolensk, Valoutina and La Moskowa
1813: Hambourg and Dresden
1814: Anvers. Arcis-sur-Aube and Saint-Dizier
1815: Waterloo
Battle honors at Auerstadt and Wagram. I guess in theory, this musket could have made it to Russia and back.
