12/31/2013. Remarks by Walter van Tilborg: "The JPV-30 Joker was an original design homebuilt aircraft of Frenchman Jean-Pierre Vintras, who also constructed the aircraft, together with Christian Arnauld.

The two-seat sport aircraft was first flown in June 1973, after a construction period of some 5 years and initially had a 90 hp Continental C90 engine. It was later re-engined with an 115 hp Lycoming O-235-C2A. The one-of-a-kind aircraft is still active and is presently in the hands of its ninth owner, Pascal Emin of Romilly-sur-Seine, France."
