The WF minis are good, & obviously excellent value. I can confirm that they're very convertable, (I gave mine torsos from Mantics Corporation Marines for my Secrets of the Third Reich Germans, the WF parts fit perfectly) & as good as the Warlord Bolt Action plastics (though they're more 'realistically' proportioned - more slender than the more 'heroically' proportioned BA stuff).
Each arm/weapon sprue if you haven't seen it contains;
16 GW98's (4 with attached rifle grenades, 2 loose with sniper optics)
7 GW43's (1 loose)
4 MG 42's
4 Panzerfaust's (2 loose)
10 MP 40's (2 loose)
4 pistols (look more like Luger's than P38's)
2 arms holding grenades
+ left arms needed to support each weapon (the guns are mostly attached to the right arms)
As to setting up a platoon, that would probably depend on which ruleset you're using, they'll all have slightly different loadouts/restrictions, but will state them clearly. You can probably generalise & say that each squad would have mostly GW 98's, (with perhaps a few GW 43's thrown in) with NCO's having the MP 40's (sadly no SGW 44's in this box) & perhaps one MG 42.
Hope that helps!
