This is All I have:
An American, John de Bruyne, bought the rights to the Gordon-Keeble and, in 1968, took space at the new York Motor Show to drum up the business. On the stand were two re-badged Gordon-Keebles and a new-mid-engined coupe which had a 5.7 Chevrolet engine, a five-speed transaxle, and a claimed top speed of 180 mph / 290 kmh. That more or less concludes the story of the De Bruyne.
