Sorensen did not understand that Ferguson was already selling a tractor mounted plow when they met in 1917

This link has a recipe for Irish potato farls. Like so many, family word of mouth mentioned being part of the colonial era migration from Ireland to Appalachia but nothing more than that.

This link documents that when Harry Ferguson met Charles Sorensen of Ford in England in 1917, Ferguson had already developed a manually lifted plow that attached to Model T tractor conversions. Sorensen was scouting a location to setup Fordson tractor production.

This is important because Sorensen's statements in his book indicate surprise at Ferguson having a working model of the plow. It reads like Sorensen did not really get that Ferguson was already selling tractor mounted plows that competed with the Fordson.
