I would not say that you've organized the various stages or periods of Cisitalia production accurately. And I would also have to say that I have found many errors in the few listings I've seen on Wikipedia. Enough errors that I would not consider it a reliable resource that should stand on its own.
Cisitalia, as a car builder directly under Piero Dusio, built cars from 1946 to 1950. But when Dusio turned over the racing cars and operation to Carlo Abarth, this was not the end of Cisitalia as a car builder. Piero was still involved even as he moved himself and some cars to Argentina to work on the Autoar projects. Carlo Dusio stayed behind and oversaw the production of a good many Cisitalia cars that should certainly still be considered true Cisitalia.
Little by little, as a cost-savings factor, the number of Fiat parts grew for many of the cars. Regardless, quite a number of Tipo 202 tube-frame cars were built 1950, 1951 and 1952. The last of them, numerically anyway, were the BPM (marine) engined cars. And, not well known yet is the fact that many of the 202 cars were built with duplicate chassis numbers. Perhaps more in the earlier (1948-1950) time period rather than later period post 1950. This means that the actual production numbers for the Tipo 202 were higher than what is implied by looking at the number range. Higher than what has been stated many times over the last twenty years or so. As incomplete as the study currently is, there are more than twenty documented cases of number duplication. Some numbers were used more than twice! I am quite certain that we will find more with additional study of period documents.
After the 202, or perhaps even during the 202's waning production, production moved toward the "DF" (derivata Fiat) cars that used Fiat chassis rather than the specially made tubular chassis that had come before. And there were a good number of projects that came along through the 1950's that had the intent of returning Cisitalia to the good times as a car builder. Didn't happen, unfortunately, but even these cars have a right to be called "Cisitalia" or at least "Fiat-Cisitalia".
In the meantime, Abarth had figured out how to be a better businessman in the market that existed and his operation managed to capture a large portion of the small market that there was, making it difficult for almost all of the other specialty builders who were in competition.
Piero Dusio took advantage of his status as a car builder in Argentina and "built" some cars in Argentina that were perhaps assembled there. Other cars clearly piggybacked on that perception and probably needed no assembly whatsoever to become badged as "Cisitalia-Argentina". This could be considered "badging" but probably should not be referred to as "production" even if some kits probably did come from the Italian Cisitalia operation.
Some of the early Abarth cars that came from Cisitalia were a mix of Cisitalia creations and Abarth (Porsche) creations built under the financial umbrella and name of Piero Dusio's Cisitalia. So, when those cars were turned over to Abarth, it is mostly a game of semantics as to whether a car should be called "Abarth" or "Cisitalia". But, these cars should not really be considered a separate stage of Cisitalia production. They were built by Cisitalia under Dusio and later modified by Abarth. A few of the cars may have been built actually by Abarth without Cisitalia involvement ... outside of some parts supply, but then those cars would not be considered "Cisitalia" at all. And I'm sure that the flow of parts went both ways.
