I had a quick search online on the usual suspects (tonton vélo, vélotaf etc...) and I can't find any more info apart from someone mentioning the whole of the 80s production was French threaded, which @grams has now shown isn't true. I also found a mention of 1989 leisure model with English threads, so the switch couldn't have happened in the 90s...

So probably good new for the OP.
