It's important to underline the fact that the "AC" list refers to individual aircraft built, not types as such.

• AC.1 was a Mignet "Pou-du-Ciel" (n° 34). It was built in five months in 1935 by Châtelain with his friend Benjamin Lefebvre. It used a 20 hp Aubier-Dunne 540 cc engine. It was unfortunately destroyed by a gust of wind two months later.
• AC.2 was another Mignet "Pou-du-Ciel" (n° 39), built in 1936.
• AC.3 was an original design, finished and flown in 1939, but was destroyed by a shell during a raid in 1940.
• AC.4 of 1948 was identical to the Gaucher/SETCA S.4 "La Mouette". Indeed, Châtelain purchased the license from SETCA and built an identical third prototype, which was registered [F-PEAB] (n° 03). It flew until it was written off in 1958.
• AC.5 "Bijou" [F-PHQO] was still flying into the 2010s, but re-engined with a 65 hp Continental A-65.
• AC.6 was a Piel CP.301 "Émeraude" built by Châtelain [F-PIIU] (n° 92), but it as destroyed in Amiens in 1962.
• AC.7 aroused interest from the military as a liaison and observation type, but it was destroyed in an accident [F-PJKO].
• AC.8 is still a mystery, but I believe it must have been at least started, because several sources say that Châtelain "built 12 aicraft including 7 prototypes".
• AC.9 [F-PMXK] has also been quoted with a 150 hp Continental O-280 engine — possibly only considered before the Lycoming?
• AC.10 was two-seat, tricyle gear version of the AC.9 [F-PPPT] (n° 01); its round tail fin was later modified with a sweep. The aircraft was lost in an accident and never rebuilt.
• AC.11 [F-PVQQ] (n° 01) has been completely restored by Sébastien Mont and still flies at Cognac-Châteaubernard, a few miles from where I live.
• AC.12 ]F-PYBO] (n° 01) was NOT a Pou type and NOT a sesquiplane, contrary to what is written further up. It was a regular biplane type.
• Finally, there was one more aircraft in the line, the Châtelain 2000 [F-PTAZ] (n° 001), a low-wing monoplane which was produced by Sébastien Mont by reusing the fuselage of the AC.12.

The Chatelain-Crépin was simply another name for the AC.4.

From Les Ailes, 2 Feb. 1954:

As soon as the great turmoil [of the war] was over, Armand Chatelain had only one thing in mind of course: building a new plane. He purchased from the Société d'Etude et de Construction d'Avions de Tourisme the set of plans and the construction license of a S.E.C.A.T. "Mouette" two-seater, which he built together with his friend Edmond Crépin.
