try old nortwest trading company.
i don't have any of their figures, but from what i've seen they're meant to go w/ FOV 21c.
they also have a set to improve on the allied armor, check out the treefrog store.
Pretty much any 1/32 scale figures. 1/35 model figures are great as tank commanders.
My favorites in 1/32 were new Britians, Old Northwest Trading Company, Toy Soldiers of San Diego (TSSD) and the old Conte WW2 figures.
