Large Brass Lantern

My father had this in the basement for over 50 years and I remember him telling me he purchased it at auction. It appears to be all brass with the exception of the added Socket and bulb as shown. The overall height of the lantern is 23" and the approximate width is 9". The glass is 2 pieces measuring overall height of 7" and combined width of 17". The flutes on the glass are approximately 5/8" wide. It has 4 brackets to hold it into some type of mount. Just a very interesting lamp which I cannot seem to locate another.
