On the ‘aerostories’ forum (http://www.aerostories.org/~aeroforums/forumhist/) Dominique Roosens has provided an encyclopaedic reply detailing the history of the entire French military fleet of Hiller UH-12s. From that it appears that the UH-12A offered for sale by auction in Paris in 2016 was not c/n 158, as that seems to have been with M Hardelet since 2002 (although the DGAC doesn’t record this as being registered F-AZJZ). It could be c/n 274, which was delivered to France, but Dominique Roosens says that this was destroyed and de-registered in 1952. So if that is the one, where was it and what was it doing for the 64 years between 1952 and 2016? Just as one thinks one is closing in on an answer, suddenly the answer seems miles away!
