The models belong to a friend who is building a War of the Roses army from Perry Brothers metals and plastics. I have never owned any Perry figures, but they live up to their reputation - well sculpted, nicely proportioned and excellent poses.
The rule set was By Arrow, Bill and Sword; a free skirmish level set put together by Silent Invader from the lead adventure forums.
Initiative and activation is determined by randomly dealt cards (visible in the background above). We added a gameplay element not specifically present in the rules, in which we laid the activation cards face down behind each unit. Players couldn't change the order of activation once a turn began, but the opponent did not know the order attack as well.
Melee was a bit slow at first. I thought it odd that a model's "to hit" number was the same no matter the quality of the attacker. The advantage for superior troops, the captain and men at arms, was mainly defensive - better save dice numbers.

Above: The battle ended when my billmen unhorsed and killed the York captain. His whole band fails a morale check, handing victory to the Lancaster forces.
The learning curve for the rules was very quick and adequately captured the flavor of the period. They could probably easily work for late HYW or Hussite Wars as well. As we were playing without cavalry units, I think another play through is in order in order to fully test the balance of troops.
