Where do I find spares for my Champion branded lawnmower?

I have a Champion branded rotary lawnmower, bought from a Do-It-All store (UK) around 1999. It has a Briggs & Stratton engine fitted and overall has served me well.

It is a Champion 46cm 3.75hp self-propelled rotary mower (serial number 6789812 and a label TD 484 TR), fitted with a Briggs & Stratton engine; model 98902, type 2180 E1, code 99102051.

I can find plenty of info ref the engine and its servicing and parts but what I really need is some spares for the body/chassis of the mower itself i.e. new front wheels and axle, new cables and return spring, etc.

I've searched for a Champion website but so far can only find lots of spark plugs!!! Grrrrr
