They look great for making up some Mordor uruks - and, glancing at the Frostgrave barbarians sprue, I can see an easy kitbash for Isengarders by adding the short, broad-bladed sword and long bow from that kit. The soldiers sprue might do the job too, as it has another couple of bow arms and three short swords. I suspect the gnoll bits will work too, as those arms fit the Wargames Factory orcs quite nicely
