PART THREE - Champion Models
For the record, I want to list what I know were Champion models.
They were not a one-model company but did try and diversify their line-up.

The 1957 ad. below identifies that year's range.
* Champion Major
* Champion De Luxe
* Champion Senior
* Champion Standard
* Champion Junior

I guess this line-up was a mix of these features: size of cut; size of engine; cooling system.
Maybe members will know something here . . .

I also include an extract from a late 1960 Champion Spark Plug booklet.
Interestingly, it gives model designation to the Rotacut range (I don't know if it is accurate).

All very interesting.
