G;day Max
I think you first raised evidence for Supa-Swift Popes.

It now appears that when Simpson-Pope ceased production
of lawnmowers in the mid-1970s, they entered some agreement with Supa-Swift
to brand Supa-Swift machines as Popes.

Your machine must be quite rare: given that Supa-Swift would, itself,
fall into new hands.

So much is unclear about this.

Cheers

p.s. I have just posted this brochure that may date the Pope-SS ...
