Very cool, CAST IRON FINIAL!  Metal fence topper, painted green, larger size for fence, measure a bit more than 5 1/2 inches tall, some noticeable wear from age and use like scuffs and scratches, rust and discoloration but still in good condition and usable.  Please be sure to carefully inspect all of the photos to see the item and to get a better idea of condition, feel free to ask questions or make offers, thanks and have a great day!!!
