OutdoorKing Repair Forum Forums Repairs and Maintenance Questions on Engines Questions On Briggs & Stratton Engines ID help please on uncommon Briggs recoil?

Can anyone tell me the story of these Briggs recoil pull starters from the 60s or 70s? Were they designed as a standalone replacement for people who had earlier wind-up starters which had broken?

As I see it, you could fit them to any "classic" style of Briggs cowl and use them like the standard recoil starter. Was this their purpose?

Or were these made for a specific kind of engine?

Any help would be greatly appreciated.
