09/30/2007. Remarks by Johan Visschedijk: "Original built as the Potez 670, powered by two 700 hp Gnome & Rhône 14 M radials, it was flown for the first time on March 30, 1939. Later it was re-engined with 800 hp Hispano-Suiza 14AB 12/13 radials, redesignated Potez 671, and flew as such for the first time in July 1939. The aircraft was destroyed during the German invasion in May 1940."
