Bronze lamp, ask for help in determining the authenticity - modern, France, Meliodon

[Marassa]

Prodaetsya vot takaya lampa with atributsiey Emile Gallé et M.Meliodon.
With glass like clear that nothing is clear , I would like to deal with the bronze. Bronze signed M.Meliodon, according to vendors in such a strange way for some reason, signed Jules André Meliodon. Well, this was Jules-André Meliodon, was born in Paris in 1867 , participated in the Salon des Beaux Arts, then moved to America. All samples that I had found on the Internet, he always signed or JA Meliodon, or Jules Meliodon, but never M Meliodon.
Further more the detective : found in the annals of the internet exactly the same lamp , but without the courtesy light , sold in the same Paris auction a year ago ! Started looking : and they did not absolutely identical, note the girl's hands !
Please note, the actual question : can there be two authentic copies , but differ in the details, or someone leads someone 's nose ? How much do you authentic is this thing , dear connoisseurs of old bronze ?
