Brass Bust Machine Age Haganuer?

Bought at a flea market a few years ago (cheap) and have been using to display vintage motorcycle helmets in my office. This is cast in many pieces and braze welded together and then filed and polished. There are no signatures , dates , or numbers on this piece. It is 17" tall and very heavy. Looking up the artist Hagenuer, (Google search) this item comes up in images but is not identified as such. I sure would like to know who produced this awesome piece!
