Case: In The Heron II
I don’t see why a distinction between the sale and transport of machinery is necessary in general. Either sale or transport could serve either use or resale of the machinery. I think you’d have to take it on a case-by-case basis.
The knowledge of a particular contract to resell the goods in question should weigh more heavily on the mind of the seller than the general knowledge that the buyer is a wheeler and dealer in the world of the widgets that are changing hands.
