10/31/2010. Remarks by Johan Visschedijk: "In March 1981 a collaborative agreement was reached between the Military Division of W. Vinten Ltd. at Bury St. Edmunds, Suffolk, UK, and Wallis Autogyros Ltd. at Reymerston Hall, Norfolk, permitting Vinten to manufacture autogyros to Wallis designs for various military and commercial purposes, this as Wallis Autogyros did not engage in production for public sale, it produced aircraft only for operation within the company.

In September 1985 two aircraft were ordered by the West German government for trials with the West German army. Based on the Wallis WA-122/R-R and initially known as Venom Mk.2s, two autogyros were completed as V-122 Libelle and flown in January 1986 at Shipdham, Norfolk."
