That is the oldest Supa-Swift I have ever seen and it is a two stroke!!
Hi Mowerfreak
It is worth doing a site search of 'Supa Swift'.
Their early machines date from the late 1950s.
They were one of the earliest users of grass catchers for rotaries.
As they were expert founders (casting) they privately made bases for
well-known mower brands (as well as their own).
A good find.------------------
