Austrian quiz

During my recent birthday extravaganza Nigel kindly gave me this superb pair of vintage Hinton Hunt Austrian generals painted by his own hand. They spent the whole of the battle as observers on a hill safe behind the allied lines and it wasn’t recorded what they thought of the Duke’s handling of events.

The one on the right (in the white coat) is general Klenau hero of Essling and the one on the left (in the blue coat) is general Gyulay who I’m reliably informed by Nigel “nearly closed the door on Napoleon’s retreat from Leipzig”.

Now, as I’m sure you’ve spotted, neither of these are actually Austrian figures but are in fact very clever conversions carried out by Nigel. So the quiz is – what base figures did he use to create these little masterpieces?
