I don't know why people selling foreign doubles can't give us a good, clear photo of the barrel flats and what's immediately in front of them. Answers a lot of questions. I'm drawn to that "Helice" 16 with the small round knob and plume rib. Don't know what the MM means. Can't say I've ever seen "toutacier" before, and don't know what the F in front of it means either. Were I looking for a French 16 and had that one in my hands to take a better look, do some measuring etc, I might take a chance on it. Price, I think, is maybe a bit on the high side.
