Was looking for something else and came across these two small images in the January 1955 issue of RAF Flying Review. Sorry about the image quality - the pics are rather small. The short description says that IAME was "currently completing the prototype...possessing a delta wing spanning approximately 32 feet and swept 70 degrees at the leading edge." Powerplant was to be a pair of either RR Avons or SNECMA Atars. Anyone know if this is actually a prototype, and not a mock-up -- and how much further it went?
