I learned through this French site the difference between a Mirage III and 5BA: the 5 has 2 pitots above the nose, while the III has them below!

Does anyone know where the REAL Mirage III No 84 is? Was it indeed 5-OM? According to scramble.nl there was a IIIC No 84, 2-EN, written off 12/1/65, so is the adopted identity of the Orange Mirage invented?
