Wargames Research Group Rules: 1685 – 1845
For many years, Wargames Research Group rules were the standard in miniature wargaming. The Wargames Rules: 1685 – 1845 cover the entire horse and musket period, and include useful army lists for Malburian and Seven-Years-War armies as well as the campaigns in India which preceded the Napoleonic Wars. I actually own a print copy of these.
