Rosieres Paul Bocuse Range Cooker needs repair

I have an old Rosieres range cooker- black, 2 ovens, cast iron top etc. it has so many problems: 1 oven does not work, the other is unreliable – you never know whether it will work or not. Neither oven doors fit, oven seals have gone, oven lights dont work, burner spark switch does not work. We are in Edinburgh and are looking for someone who can give it a full repair. Any help / contacts much apreciated.
