I found these excellent metal figures at Irregular Miniatures (a prolific UK figure manufacturer).
These are from their 20mm range for Garibaldi Wars.

I based them high so they would work alongside my 20-25mm 1/72 figures.

You can easily get French post Crimea as that uniform pretty much ran until 1914.

I use Field of Battle Piquet basing of 4 bases per battalion. This also neatly matches Neil Thomas rules for the 19th century european wars. I also like to have the officers separate so they can gross up to show brigade commands. Piquet also allows strong and weak battalions, 3-5 bases is possible. Neil Thomas does not like command explicitly on show, so there are no issues there.

The reality is that between 1815 and 1854 the French had uniform changes like so many cups of tea – sorry that should be coffee of course.
The Funcken shown is an excellent book that shows the colourful story of French fashions from shako to kepi and breeches to pantaloons!
