Hi John,
These are aimed at the early to mid 13th century rather than late fifteenth century - so they are about 200 years out in terms of armour, weapons etc. and the difference is as great as using WW1 figures to represent present day Western troops in Aghanistan.
The Perrys have some plastic WotR knights in the Rhendra queue, probably due out close to Salute in April. it's worth holding out for them I'd say.
Now if you were after the Second Barons' War - Simon de Montfort and Edward Longshanks, then they would be ideal.
Regards,
