Hello
M-o-K and
Sir ChookI can only agree with Sir Chook's assessment.
I can't say whether the design originates with the Suffolk Foundry
or with Qualcast (who acquired them).
I think the design that I recognise first appeared as the
Royal Blade, the replacement for the Qualcast 16 Power Mower.

I'm thinking this became the Commodore when 4-strokes were adopted in the 1960s.
