The bottom photograph is unique. It shows the version of the Amiot with the Rolls Royce Merlin. The Merlins were to be built by Ford in France but with the Armistice the Germans captured the lot including the drawings. Seemingly the aircrafts performance with Merlins was astonishing. But like everything at the time it was too little too late. We had to wait another four years to give the Nazi's a good thumping
Sorry, C1951, but bottom pic shows the unique Amiot 370 with Hispano V-12 engines (see exhaust pipes !)
