ANTIQUE ORIGINAL LIGHTNING ROD Fence Top Salvage Heavy Metal ARROW. I am completely unsure what this came off of. What I can tell you is that it's heavy like cast iron, but it seems like it is a heavy aluminum metal based on the black wearing away and the silver coming through but it is very solid. It's not light like an aluminum usually is. This can be used for many different things including just wall decor if you want. It needs your imagination. I have five of them available in the same condition with the wear just in different spots. But all in all I would say very nice for its age. This piece measures 24 inches tall and the two decorative spots are 3.75 in wide. Please see all photos. If you have any questions please ask. Happy bidding and good luck!
