my recollection is that models 104, 105 and 105bis received the 22mm removal threads directly at their 1977 launch
can recall purchasing two 104 sets new in 1978 from a local distributor and found them to be the 22mm
do others recall something different?

I went back and double checked the literature. The first catalogue to mention 22mm extractors is #26, which is reportedly for the 1982 model year. The cranksets in this catalogue appear to be a mix of 22mm and 23.35mm extractors. The 106, 104 and 99NM specifically mention the 22mm extractor while the 105, TS and 49 variants do not mention the extractor style. I take this to mean that these three older models still used the old 23.35mm extractor. I believe the NM designation on the 99 indicates
nouvelle modele or something similar, to designate the transition from a 23.35mm to 22 mm extractor.
By catalogue #27 (for the 1983 model year), all the cranksets specify 22mm extractors. The 105, TS and 49 variants are not included and appear to have been discontinued.
This falls mostly in line with the statement in Sutherland's which specifies the 23.35 extractor for pre-1982 Stronglight crankset and 22mm extractor for 1982 and newer. However, the factory literature doesn seem to suggest that there was at least one transition year.
I could find no case of a 105/105BIS that specified 22mm extractors. I found it in four catalogues that are reportedly for 1976, 1978, 1980 and 1982.
While the 104 specified 22mm extractors, I could find no evidence of it existing in 1978. The earliest reference is catalog #27, which is reportedly 1982. However, this is arguable, as the reportedly 1980 Peugeot catalog contains models with 104 cranksets. So, maybe the catalogues have not been accurately dated? Or did Peugeot get exclusive use for a period, prior to general commercial availability? Unfortunately, the Peugeot catalogue has no dating (model year, copyright date or publishing date) on it. Similarly, prior to catalog #28, none of the Stronglight catalogues are marked with dates.
Regardless, based on the factory literature, there only appears to have been two different extractor threadings, 23.35mm and 22mm. The 23.35mm extractor was used on all the non-1xx series cranksets and the 105 variants. The 22mm extractor was used on all the 1xx series cranklsets, with the exception of the 105 variants. The only crankset to be offered for both extractor threadings were different versions of the 99.
