You will need to do a search for : Crystal Palace Orpington Poultry
You will see pictures that are for sale of the winners from when there use to be very big shows in the UK. Mr Rice is selling such pictures which are copywright so do not copy them and publish on any sites. As you can see the UK type has been there for very many years.
