That is the one TheiC. The SO M2.
The French Air Force drew up a requirement for a jet bomber shortly after then end of the Second World War, with the new bomber expected to have a weight of about 25–30 tonnes and to fly at high-subsonic speeds. Designs were tendered by SNCASO, the SO 4000 and by SNCAC, the SNCAC NC 270, which resulted in SNCASO receiving an order for two manned scale models, the first, the SNCASO M.1 - an unpowered glider which would be tested from atop the first prototype of the Heinkel He 274 which had remained in France post-war and restored to flightworthiness by the French, while the SNCASO M.2 was powered by a single Rolls-Royce Derwent.
