As you can see, I've been trawling about on German eBay for flats.
I'm not getting too hung up on figure ratios and all that sort of thing. As far as I am concerned, one stand is a squadron, battalion or battery. To my eye about four cavalry look good, as do a dozen infantry or a single gun.
Things are not too far along at the moment; I'm really just playing around with the aesthetics of the thing. That said, I envisage using mini dice to record combat attrition. I also envision using written orders that may be deviated from through the expenditure of initiative tokens. Different armies might have different numbers of them to expend per turn. I would expect the Prussians to have more than the Austrians who, in their turn might have more than the French.
Any feedback would be highly valued.
