I picked up a box of Victrix Imperial Guard for the Black Powder game I've been planning. The French reserve brigade will combine one regiment of Imperial Old Guard Grenadiers a pied and Imperial Guard cavalry (still to be decided).
The Victrix set is less 'fiddly' than the line regiment set with less construction required. The Old Guard are one of those units that everyone has to have in their collection; Highlanders, 95th Rifles & Scots Greys probably filling the same role for the British.
Also on the shopping list recently was the Perry Hussar set. I've chosen the 7th Regiment positioned on the left of Napoleon's lines at Waterloo. The buttoned trouser overalls are green based on a plate from '|The Waterloo Companion' although there is conflicting information from Mont-Saint-Jean and other sources that suggest the overalls should be red.
