need new gas tap/regulator for it.it would normally be written it off but its a relatives, in amazing condition and they love the massive oven and really would liek not to have to replace it as all the new gas single ovens are tiny inside. probs about 30 years old. if any one knows the orginal part no, or can suggest an alt part that would work it would be great. connect dont have a listing for hte model, let alone any spares… 🙁
