These 33 figures represent all 11 Russian hussar regiments. I spent a couple of days looking through my sources and compiling regimental colors for all of these, only to find my information duplicated at Blunders on the Danube! So far as I can tell, Peter is right on with his regimental distinctions.
White Russia Hussars
Only 15 figures of guard cavalry remain to be painted, although Glenn has added on the Czar and the Austrian emperor, so I will probably include those figures when I ship these off.
