Glasmaken Lexicon, usually pretty reliable, has it as A Mazoyer
and says he was based in the city of Moulins regional capital of Allier central France, in a shop called 'Nouvelle Galerie' 1910-45 -possibly with a Paris shop too c1930.
And as moulins are windmills it would explain the windmills often on the signature
The Lexicon sites the main source for this as a ceramics book as they did ceramics too
