Doh - having looked at all the listings again it would appear that everybody is selling pairs of door cards and 1/4 panels, the Rimmers description is the only one that expressly says that they are priced as a pair which would make them nearly half the price of the others.
as Rob P says these all seem to be made by Newtons and as Paddocks are a good price and have always been great in terms of service and price an order is going in to them.
Thanks for all your help.
John
