A mix of C-o-A´s, some based on reality, some, as far as my Research has led me, made up.The ones with a base in reality.
The three black bars on yellow? Used by quite a few places and People. The town arms of Inchy-en-Artois, Puygouzon, Beutal or the Family arms of Corbel Corbeau de Vaulserre or Kielmansegg among others but the Dates aren´t certain and some appear after the medieval period or later.
I found one or two Patterns which could fit the C-o-A of the bod in the middle, ie; John Lovel, whose C-o-A appears in the Falkirk Roll. Barry wavy, or and gules but his has eight "waves", not six as shown and starts with yellow at the top, not red.
The one on the left of the pic is Valdemar (resin) The other 2 are metal and unknown make(s)
