I have a New World inbuilt gas cooker. Grill at eye level, oven below. It's old - was in the property when I bought it. The springs on the (drop down) oven door have gone. I don't want to buy a new oven (I need to try and eke it out for 2 or 3 months) and I can't order new hinges because I don't know the model of the oven. I have looked for the model number everywhere; even had the whole appliance out of the casing. I have a photo of the oven and springs (though can't attach it on this discussion board). Can anyone help please?
