I wasn't doubting you, Deejay, and anyway the colour was wrong. The Qualcast started off with a block-tread on the tyres, but it soon wore off and left them bald, which was actually better because you had to hold the mower back a bit when mowing - the gearing between wheels and reel was wrong, and it left cut-marks if you let it have its head. The Pope in the picture looks as if it has bald tyres too.

I suspect they were the same mower badge-engineered.
