I also have a broken outer glass but found the model is no longer made and spares are only kept for 10 years. My model is 13 years old. If you are within 10 years then order the spare from Stoves PLC through a dealer, you cannot order direct eg kitchen suppliers or caravan suppliers. Your model number and serial number should be on the main frame of the oven on a metal plate just to the left behind the door. Good luck
