Marcel Bloch dies in the Buchenwald concentration camp. Perish the French aircraft industry after WW2? Probably not but what happens to it? You still have Breguet, you still got the French public companies, you still have Morane Saulnier and Potez trying to get back into business. Henry Potez given his close ties with Bloch seems a logical candidate to take over the Bloch facilities which gives him industrial facilities, unlike OTL.
And then what? The French public companies licence build Vampire and Sea Venom, while their plans for domestic designs like VG.70/80/90 fail miserably. Does an Ouragan clone come out of the now Potez factory? Perhaps or perhaps Morane's paper projects sees the light of day or just as likely the French end up with a delayed Mystere equivalent by 1954. Things are perhaps more straightforward later on. By1955 Breguet dies, if Potez has gone into business it would be reasonable to see his company merging with Breguet to form an alternative to Sud Aviation. The Breguet 1120 looks, at least on paper a reasonable alternative to both Mirage III and Mirage F1, Breguet 1180 or 120 likely take the niche of Mirage IV.
Which has brought us potentially to the mid-late 1960s. Where one notes Breguet in OTL did work together with BAC/Bristol and was less adverse to it than Dassault. If this carries on the the TTL Potez-Breguet...
