Rangemaster Kitchener 90 Oven / Hob

Rangemaster Kitchener 90 Dual Fuel Range Gas Cooker. Beast of a machine. 3.5yrs old. **Have owned it 1.5yrs ourselves, but was unused for year before that so the grill/oven currently doesn't work but im guessing its lack of use before we came to the house too. No issue with Hob and extractor fan we use it all the time.** It will defo need a bit of tender loving but it will be 100% worth it afterwards. We thought about it ourselves but new would be getting our kitchen done and its a little bit too big for what we are doing. Any questions, let me know.
