All of these are wrong: there is no evidence that any of these designation was really allocated to a design. Please remove your speculations.
Only the X-121 is an unknoxn design, as it is mentioned in a list from a subcontractor that also worked for it. The other ones are pure inventions from your side.
In 1963, Aviation Magazine published a 5 part essay on the MB/SE/SO 161. While researching, I had GPT translate it for me. I've collected the story verbatim in a Word doc.

1963 Aviation Magazine SE.161 full 5part story .docx
SE.700 Alouette was a three-seat passenger autogiro, powered by one 330 hp Béarn 6D-07 engine. 4 ordered, 1 built, 1st flight 25th May 1945 SE.701 Alouette A was a version of the SE.700, intended to carry 700 kg of load, powered by one 220 hp Renault 6Q-01 engine, also known as SE.700A. Project only
Hello @PhR. Great list and great starting point for research. The evidence I found for the 700 and 700A points to the 220hp for the 700 and the 330hp for the 700A. Makes sense to have a smaller engine to start off with. Small stuff. See the 1946 Les Ailes article. And the translation I had GPT generate. Agree?
Then again. The prototype that actually flew was a 330hp Bearn....would that lead to a conclusion that it was the 700A that flew? Or actually the B version? Mhh...
According to Les Ailes in 1948, there was an SE.3010 helicopter "study", yet the table also states that one was built. It had a 100hp Mathis G4R engine, and we all know that in 1948, the 3101 flew with a 100hp Mathis. This leads me to a cautious conclusion that the 3010 was renamed 3101. Any other info around these models?

This is a book of 2004 by a man called Stanley McGowen. There is a mention of the 3010 again, but if you read the full paragraph, you can clearly see that it is a typo and that, in this case, it refers to the 3110.
You are right. The information probably comes from Pierre Gaillard's book:
Google translate:
Designed in 1943 by Pierre Satre, according to the same program as the SO.3050, the first prototype of this two-seat trainer, the SE.2300 No. 01 F-WBBD, carried out its first tests in Toulouse, piloted by Pierre Nadot. A second aircraft, with tricycle landing gear, the SE.2310 No. 02 F-WBBK (later F-BBBM), flew on 31-12-45. It was followed by the SE.2310 No. 03 F-BEEL, converted to a three-seater, as well as an SE.2311 with a 135 hp Régnier 4L-00 engine.
These aircraft designs were abandoned after the selection of the Nord N.1200 "Norécrin" during the February 1946 tourist aircraft competition. SE.2300:1 Renault 4 Pei 140 hp engine
However, it is not confirmed in SNCASE presentation document:

GENERAL INFORMATION.
The SE.2.311 aircraft is a three-seat touring aircraft. It is designed to make learning and practicing flying accessible to a large number of people. It is derived from the 2.300 and 2.310 aircraft, from which it differs:
compared to the 2.310 by the construction method
compared to the 2.300 by the tricycle landing gear instead of a single landing gear, three-seat instead of two-seat, wing fuel tank instead of fuselage fuel tank, doors instead of a canopy, construction method
The SE.2311 is a version of the SE.2310 whose construction method has been improved to facilitate mass production.
I will modify my list accordingly.
I'm tying up loose ends on my SNCASE-Sud Aviation listings. I agree that the French notation system is daunting by any standard. So, i use other elements to identify the design, like type, year, seats, pax, engine, use. This brings me to X.305 once again. I have of course read the thread here and I like to stay away from whether or not it has existed. I believe it has.
I have however a question about the listing itself.
A medevac helicopter would not need 2x3000shp engines. That is a very heavy lift.
Turbomeca at that time did imho not work on such an engine.
These days I use Claude and no longer GPT. Claude is more accurate and makes less mistakes. Besides, I've found these Turbomeca engines across the SE-SA range. None of them are 3000shp. I will consider that a typo and leave my engine listing as ...shp Turbomeca.
No merges please, opportune or unwarranted; one set of posts is about SNCASE designations & one set of posts is about SNCASE projects. Reckless & willy-nilly merging has already ruined my own carefully curated contributions to this website over the years and I hardly ever post anything here as a result.
