Good suggestion Alex, but these legs do not match the armour and flag colour. Their blue is a bit darker... I am using these 3899 legs on another project...The ones I am using in the eagle knights, and taken from the cossack special btw,are the perfect ones for knights. Its like the tunic (fabric) comes down to the side of the legs and covers the chain mail armour!
The torsos I am using is from 3030! I had bought four of them last year! That leaves one more knight to make...hmmm
Yes, I believe Playmobil had that idea when they made them.
It is called a surcoat.
Great Customs by the way.
Perhaps they could be part of an Order of Knights,
Like the Templar Order, except they work for the King.
They accept the best Knights and train them to be like a crack force.
