I have a French 19th C(?) green cut crystal glass perfume bottle with a silver top. It is marked with a lozenge and I cannot figure out the last letter of the makers mark nor the symbol in the center. The first letter looks to be a J but I am thinking that the last is an M or E[?]? Do you see this as well? Anyone recognize the maker? I also included photos of the fineness mark (Boars head) but what is the mark below it? A counter hallmark? I have included multiple photos which I hope give a better view of the makers mark, I had to use my microscope to get close enough to capture the marks and this is the best I can do. Thank you!
