The BBC have told me the Rembrandt house is on their annual auction page at Ebay. If you copy and paste the below link you can find it. All proceeds to Children in need. I know it has a few hundred pounds worth of items in it, some specially made and one of a kind, so we’ll worth a bid. I have even had a few bids myself!
