Emile Galle desk lamp - France, Art Nouveau

Hello all, I recently acquired this desk lamp and was hoping someone knowledgeable could tell me more about it. The lamp stand appears to be bronze, is 15" tall, and has a screw with "ASG" marked on the top. The glass shade is signed Galle and has a circumference of 14" and height of about 4.5". It works as it should and glows to a beautiful orange/red sunset color when lit.

Does anybody know who made this lamp, or when? I realize the glass is by Galle but have no idea about the lamp itself. There are no other markings that I could locate other than what I have mentioned above. Thanks for helping!
