Bronze Putti Lamp w/Candle Holders and Electric and Cut Glass

I believe it to be bronze. The Putti is holding up the top part of the lamp which is a cut glass globe with candle sticks (4) and two electic lights above that. There is no finial or shade. The Putti is kneeling on another cut glass globe. There is ornate scroll work on what constitutes the candle holder, possibly laurel leaves. There is some discoloration around the base. The Putti is in nice condidtion the candle stick and holders are not damaged. The only damage is the discoloration. There is no signature but where the base is attached underneath is printed pat pend.I can't find any chips or cracks in the glass. It is in as found condition, I haven't cleaned at all.  I don't know much about lamps and bought this to use on a table in the garden with candles. Any information is appreciated.
