Ros, I've just checked out the make of our S & L.

I bought ours at a local garden centre, but I've checked and you can got it on Amazon.
The grandkids seem to like the board.
I've never been to Norwich Cathedral, although I've always intended to do so. Whenever we've been to Norwich (we stay on holiday in Lowestoft in Suffolk, so not too far away) we have always had the dog with us, so visiting the Cathedral and the Castle are not viable propositions.
