Rangemaster Excel dual Fuel Range Cooker

Initially a very attractive cooker - but the looks have not lasted. The control panel started wearing away on the controls most use a few months after purchase, and several months later has not been replaced. Rangemaster say they will replace, but they have none in stock. It is now difficult to see which knob relates to which ring and the temperature and settings for the ovens. Apart from that the cooker itself is OK, but not as good as my previous Rangemaster from 10plus years ago. Also the third "oven" is not big enough to be of use, and is only of use as a warming oven.
