cardboard foldable slide (Riverdene RG21)

Hello everyone. I am looking for one of these cardboard slides for my grandson. Does not matter on design. If your children have outgrown it. another younger young man would be very pleased to enjoy it. Or can anyone tell me where I could purchase one new or second hand. would prefer second hand so giving more life to it. I have been unable to find any in the UK. Thank you for any help. regards Anne
