Cuirassiers, Chevauxleger and Hussars. Unit identification is based on this source: http://www.napoleonguide.com/cavalry_austria.htm
Regt No 4 Von Recsey, Regt No 10 Meszaros and Regt No 2 Erzherhog Joseph
Minifigs has the trumpet slung over the shoulder, but pretty standard apart from that.
By the look of the basing I'm guessing that this was meant to be one unit.
Base size is 20mm by 40mm which is the effective WRG Wargames Rules 1685-1845 or Horse and Musket basing sizes. The Hussars are on plasticard.
A generic Chevauxleger unit of 12 figures.
Broken standard bearer, standard poses.
Apart from the missing standard, they appear to be in good nick.
Basing for casualty removal (and swapping back in as required).
Same basing as the Hussars, although slightly rounded corners.
One of possibly four Cuirassier regiments.
No flags, but flag poles. However trumpets are broken.
Stock standard Minifig poses. I feel sorry for the poor trumpeter.
Again the same basing configuration, possibly for two six figure strong units (although a quick check of WRG has a unit as 12 trained cuirassiers).
20mm by 40mm but metal this time.
