A look at Deus Vult Medieval miniatures from Fire Forge. Might they be a good proxy for Bretonnians? 

A closer look at some of the Deus Vult Western Army Medieval plastics from Fire Forge. A chat about how to build them, base them and which armies they might be useful for. Late Crusaders, early Hundred Years Wars, War of the Roses or maybe even a proxy Bretonnian army.
