The real thing are these Tirallieurs Algerien from Hong-Kong Japanese infantry!!! Same goes for Zouaves.
And at least some Austrian Ulans in Kittel.
So with French lineinfantry and other units available from Emhar and Strelets and several plastics as well as the good Bersaglieri from Waterloo and Italian line from Lucky-Toys the realisation of such a diorama comes closer. Just good Austrians are still needed.
