Petrol lawnmower (Malvern Link WR14)

Hi, I am looking for a petrol lawnmower, self-propelled NOT one that is driven along by the wheels. Ideally around 40cm/ 16" cut. Preferably working but if someone has one that need a little TLC that might do, also no more than 10years(?) old as if I need parts they may no longer be available. Thanks
