Sorry windriver,after all your hard work evansb comes up with the answer. It is the Fouga CM.8 Sylphe (Cyclone).
The C.M. 8R-13 Cyclone is a jet-powered version of C.M. 8-13 Sailplane. The C.M. 8R-13 had been intended to serve as a test-bed for the Turboméca Piméné light axial-flow turbo-jet engine which has a maximum static thrust of 100 kg. (220 lb.). I hope my replies to your theories did not led you off at a tangent.
Bri you have control, with that answer you have just passed cringe's score.
