Someone using the name of Jérome Poinsu Joubert is currently trying to sell an Acadian D Black accordion on a few websites in France:
This particularly one has been effectively sold a few months ago legally in "le bon coin" website (sort of french Craiglist), and the scammer uses the same text add and the same photographs .
I suspected something wrong with this add (see website link # 1), so I asked how was the sound with all four stops down , and he answered the sound to be excellent !!! :-)))
