My Georland Army will use Minifigs S Range French figures, mainly Franco Prussian War but augmented by some Crimean War red trouser era (Second Empire). This seems appropriate as George Alfred Keef's soldiers were Franco Prussian War types bought in bilk in the 1870's, although his figures were German-made 40mm demi-rondes.
So we will start with these Crimean figures:
Imperial Guard Infantry
Zouaves and Turcos (the same figures, just different paint jobs)
Then the Franco Prussian War Infantry units:
Chasseurs a Pied
Turcos (the same figure with a different paint job)
Line Infantry (three battalions)
I still have to further research the Georland Order of Battle and work out which units these figures can represent.
