HaT Württemberg Infantry 100x figs
HaT Württemberg Cavalry 12x cavalry
HaT Württemberg Artillery 16x figs and 4 guns
yes I know the artillery set has a pitiful crew but perhaps Oronegrean gunners were super efficient like F1 pit crews today. also the infantry are great you can either go to PSR or perhaps you can visit this section of the HäT site. I like the infantry set because of the Ratio of figure types; 40 infantry in helmets, 20 light infantry/ scouts (they will get tricorns or other suitable head gear) and 16 grenadiers (will get tricorns) also not to mention the NCO's officers and drummers that bring this set up to full strength.
so perhaps these men will be our Oronegreans instead. but your advice would be more than welcome.
